+# Rojo Changelog
+
+## Unreleased Changes
+* Updated reflection database and other dependencies.
+
+## [0.5.4](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.4) (February 26, 2020)
+This is a general maintenance release for the Rojo 0.5.x release series.
+
+* Updated reflection database and other dependencies.
+* First stable release with binaries for macOS and Linux.
+
+## [0.6.0 Alpha 1](https://github.com/rojo-rbx/rojo/releases/tag/v0.6.0-alpha.1) (January 22, 2020)
+
+### General
+* Added support for nested project files. ([#95](https://github.com/rojo-rbx/rojo/issues/95))
+* Added project file hot-reloading. ([#10](https://github.com/rojo-rbx/rojo/issues/10)])
+* Fixed Rojo dropping Ref properties ([#142](https://github.com/rojo-rbx/rojo/issues/142))
+    * This means that properties like `PrimaryPart` now work!
+* Improved live sync protocol to reduce round-trips and improve syncing consistency.
+* Improved support for binary model files and places.
+
+### Command Line
+* Added `--verbose`/`-v` flag, which can be specified multiple times to increase verbosity.
+* Added support for automatically finding Roblox Studio's auth cookie for `rojo upload` on Windows.
+* Added support for building, serving and uploading sources that aren't Rojo projects.
+* Improved feedback from `rojo serve`.
+* Removed support for legacy `roblox-project.json` projects, deprecated in an early Rojo 0.5.0 alpha.
+* Rojo no longer traverses directories upwards looking for project files.
+    * Though undocumented, Rojo 0.5.x will search for a project file contained in any ancestor folders. This feature was removed to better support other 0.6.x features.
+
+### Roblox Studio Plugin
+* Added "connecting" state to improve experience when live syncing.
+* Added "error" state to show errors in a place that isn't the output panel.
+* Improved diagnostics for when the Rojo plugin cannot create an instance.
+
+## [0.5.3](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.3) (October 15, 2019)
+* Fixed an issue where Rojo would throw an error when encountering recently-added instance classes.
+
+## [0.5.2](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.2) (October 14, 2019)
+* Fixed an issue where `LocalizationTable` instances would have their column order randomized. ([#173](https://github.com/rojo-rbx/rojo/issues/173))
+
+## [0.5.1](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.1) (October 4, 2019)
+* Fixed an issue where Rojo would drop changes if they happened too quickly ([#252](https://github.com/rojo-rbx/rojo/issues/252))
+* Improved diagnostics for when the Rojo plugin cannot create an instance.
+* Updated dependencies
+    * This brings Rojo's reflection database from client release 395 to client release 404.
+
+## [0.5.0](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.0) (August 27, 2019)
+* Changed `.model.json` naming, which may require projects to migrate ambiguous cases:
+    * The file name now takes precedence over the `Name` field in the model, like Rojo 0.4.x.
+    * The `Name` field of the top-level instance is now optional. It's recommended that you remove it from your models.
+    * Rojo will emit a warning when `Name` is specified and does not match the name from the file.
+* Fixed `Rect` values being set to `0, 0, 0, 0` when synced with the Rojo plugin. ([#201](https://github.com/rojo-rbx/rojo/issues/201))
+* Fixed live-syncing of `PhysicalProperties`, `NumberSequence`, and `ColorSequence` values
+
+## [0.5.0 Alpha 13](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.0-alpha.13) (August 2, 2019)
+* Bumped minimum Rust version to 1.34.0.
+* Fixed default port documentation in `rojo serve --help` ([#219](https://github.com/rojo-rbx/rojo/issues/219))
+* Fixed BrickColor support by upgrading Roblox-related dependencies
+
+## [0.5.0 Alpha 12](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.0-alpha.12) (July 2, 2019)
+* Added `.meta.json` files
+    * `init.meta.json` files replace `init.model.json` files from Rojo 0.4.x ([#183](https://github.com/rojo-rbx/rojo/pull/183))
+    * Other `.meta.json` files allow attaching extra data to other files ([#189](https://github.com/rojo-rbx/rojo/pull/189))
+* Added support for infinite and NaN values in types like `Vector2` when building models and places.
+    * These types aren't supported for live-syncing yet due to limitations around JSON encoding.
+* Added support for using `SharedString` values when building XML models and places.
+* Added support for live-syncing `CollectionService` tags.
+* Added a warning when building binary place files, since they're still experimental and have bugs.
+* Added a warning when trying to use Rojo 0.5.x with a Rojo 0.4.x-only project.
+* Added a warning when a Rojo project contains keys that start with `$`, which are reserved names. ([#191](https://github.com/rojo-rbx/rojo/issues/191))
+* Rojo now throws an error if unknown keys are found most files.
+* Added an icon to the plugin's toolbar button
+* Changed the plugin to use a docking widget for all UI.
+* Changed the plugin to ignore unknown properties when live-syncing.
+    * Rojo's approach to this problem might change later, like with a strict model mode ([#190](https://github.com/rojo-rbx/rojo/issues/190)) or another approach.
+* Upgraded to reflection database from client release 388.
+* Updated Rojo's branding to shift the color palette to make it work better on dark backgrounds
+
+## [0.5.0 Alpha 11](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.0-alpha.11) (May 29, 2019)
+* Added support for implicit property values in JSON model files ([#154](https://github.com/rojo-rbx/rojo/pull/154))
+* `Content` propertyes can now be specified in projects and model files as regular string literals.
+* Added support for `BrickColor` properties.
+* Added support for properties added in client release 384, like `Lighting.Technology` being set to `"ShadowMap"`.
+* Improved performance when working with XML models and places
+* Fixed serializing empty `Content` properties as XML
+* Fixed serializing infinite and NaN floating point properties in XML
+* Improved compatibility with XML models
+* Plugin should now be able to live-sync more properties, and ignore ones it can't, like `Lighting.Technology`.
+
+## 0.5.0 Alpha 10
+* This release was a dud due to [issue #176](https://github.com/rojo-rbx/rojo/issues/176) and was rolled back.
+
+## [0.5.0 Alpha 9](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.0-alpha.9) (April 4, 2019)
+* Changed `rojo build` to use buffered I/O, which can make it up to 2x faster in some cases.
+    * Building [*Road Not Taken*](https://github.com/rojo-rbx/roads) to an `rbxlx` file dropped from 150ms to 70ms on my machine
+* Fixed `LocalizationTable` instances being made from `csv` files incorrectly interpreting empty rows and columns. ([#149](https://github.com/rojo-rbx/rojo/pull/149))
+* Fixed CSV files with entries that parse as numbers causing Rojo to panic. ([#152](https://github.com/rojo-rbx/rojo/pull/152))
+* Improved error messages when malformed CSV files are found in a Rojo project.
+
+## [0.5.0 Alpha 8](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.0-alpha.8) (March 29, 2019)
+* Added support for a bunch of new types when dealing with XML model/place files:
+    * `ColorSequence`
+    * `Float64`
+    * `Int64`
+    * `NumberRange`
+    * `NumberSequence`
+    * `PhysicalProperties`
+    * `Ray`
+    * `Rect`
+    * `Ref`
+* Improved server instance ordering behavior when files are added during a live session ([#135](https://github.com/rojo-rbx/rojo/pull/135))
+* Fixed error being thrown when trying to unload the Rojo plugin.
+* Added partial fix for [issue #141](https://github.com/rojo-rbx/rojo/issues/141) for `Lighting.Technology`, which should restore live sync functionality for the default project file.
+
+## [0.5.0 Alpha 6](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.0-alpha.6) (March 19, 2019)

+* Fixed live server not responding when the Rojo plugin is connected ([#133](https://github.com/rojo-rbx/rojo/issues/133))
+* Updated default place file:
+    * Improved default properties to be closer to Studio's built-in 'Baseplate' template
+    * Added a baseplate to the project file (Thanks, [@AmaranthineCodices](https://github.com/AmaranthineCodices/)!)
+* Added more type support to Rojo plugin
+* Fixed some cases where the Rojo plugin would leave around objects that it knows should be deleted
+* Updated plugin to correctly listen to `Plugin.Unloading` when installing or uninstalling new plugins
+
+## [0.5.0 Alpha 5](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.0-alpha.5) (March 1, 2019)
+* Upgraded core dependencies, which improves compatibility for lots of instance types
+    * Upgraded from `rbx_tree` 0.2.0 to `rbx_dom_weak` 1.0.0
+    * Upgraded from `rbx_xml` 0.2.0 to `rbx_xml` 0.4.0
+    * Upgraded from `rbx_binary` 0.2.0 to `rbx_binary` 0.4.0
+* Added support for non-primitive types in the Rojo plugin.
+    * Types like `Color3` and `CFrame` can now be updated live!
+* Fixed plugin assets flashing in on first load ([#121](https://github.com/rojo-rbx/rojo/issues/121))
+* Changed Rojo's HTTP server from Rouille to Hyper, which reduced the release size by around a megabyte.
+* Added property type inference to projects, which makes specifying services a lot easier ([#130](https://github.com/rojo-rbx/rojo/pull/130))
+* Made error messages from invalid and missing files more user-friendly

+* Changed Windows builds to statically link the CRT ([#89](https://github.com/rojo-rbx/rojo/issues/89))
+
+## [0.5.0 Alpha 3](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.0-alpha.3) (February 1, 2019)
+* Changed default project file name from `roblox-project.json` to `default.project.json` ([#120](https://github.com/rojo-rbx/rojo/pull/120))
+    * The old file name will still be supported until 0.5.0 is fully released.
+* Added warning when loading project files that don't end in `.project.json`
+    * This new extension enables Rojo to distinguish project files from random JSON files, which is necessary to support nested projects.

+
+## [0.5.0 Alpha 1](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.0-alpha.1) (January 25, 2019)
+* Changed plugin UI to be way prettier
+    * Thanks to [Reselim](https://github.com/Reselim) for the design!
+* Changed plugin error messages to be a little more useful
+* Removed unused 'Config' button in plugin UI
+* Fixed bug where bad server responses could cause the plugin to be in a bad state
+* Upgraded to rbx\_tree, rbx\_xml, and rbx\_binary 0.2.0, which dramatically expands the kinds of properties that Rojo can handle, especially in XML.
+
+## [0.5.0 Alpha 0](https://github.com/rojo-rbx/rojo/releases/tag/v0.5.0-alpha.0) (January 14, 2019)

+    * This helps prevent syncing in content to the wrong place
+    * Multiple places can be specified, like when building a multi-place game
+* Added support for specifying properties on services in project files
+
+## [0.4.13](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.13) (November 12, 2018)
+* When `rojo.json` points to a file or directory that does not exist, Rojo now issues a warning instead of throwing an error and exiting
+
+## [0.4.12](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.12) (June 21, 2018)
+* Fixed obscure assertion failure when renaming or deleting files ([#78](https://github.com/rojo-rbx/rojo/issues/78))
+* Added a `PluginAction` for the sync in command, which should help with some automation scripts ([#80](https://github.com/rojo-rbx/rojo/pull/80))
+
+## [0.4.11](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.11) (June 10, 2018)
+* Defensively insert existing instances into RouteMap; should fix most duplication cases when syncing into existing trees.
+* Fixed incorrect synchronization from `Plugin:_pull` that would cause polling to create issues
+* Fixed incorrect file routes being assigned to `init.lua` and `init.model.json` files
+* Untangled route handling-internals slightly
+
+## [0.4.10](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.10) (June 2, 2018)

+* Fixed obscure error when syncing into an invalid service.
+* Fixed multiple sync processes occurring when a server ID mismatch is detected.
+
+## [0.4.9](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.9) (May 26, 2018)
+* Fixed warning when renaming or removing files that would sometimes corrupt the instance cache ([#72](https://github.com/rojo-rbx/rojo/pull/72))
+* JSON models are no longer as strict -- `Children` and `Properties` are now optional.
+
+## [0.4.8](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.8) (May 26, 2018)
+* Hotfix to prevent errors from being thrown when objects managed by Rojo are deleted
+
+## [0.4.7](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.7) (May 25, 2018)
+* Added icons to the Rojo plugin, made by [@Vorlias](https://github.com/Vorlias)! ([#70](https://github.com/rojo-rbx/rojo/pull/70))

+
+## [0.4.6](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.6) (May 21, 2018)
+* Rojo handles being restarted by Roblox Studio more gracefully ([#67](https://github.com/rojo-rbx/rojo/issues/67))
+* Folders should no longer get collapsed when syncing occurs.
+* **Significant** robustness improvements with regards to caching.
+    * **This should catch all existing script duplication bugs.**
+    * If there are any bugs with script duplication or caching in the future, restarting the Rojo server process will fix them for that session.
+* Fixed message in plugin not being prefixed with `Rojo: `.
+
+## [0.4.5](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.5) (May 1, 2018)

+* Partitions targeting files directly now work as expected. ([#57](https://github.com/rojo-rbx/rojo/issues/57))
+
+## [0.4.4](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.4) (April 7, 2018)
+* Fix small regression introduced in 0.4.3
+
+## [0.4.3](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.3) (April 7, 2018)
+* Plugin now automatically selects `HttpService` if it determines that HTTP isn't enabled ([#58](https://github.com/rojo-rbx/rojo/pull/58))
+* Plugin now has much more robust handling and will wipe all state when the server changes.
+    * This should fix issues that would otherwise be solved by restarting Roblox Studio.
+
+## [0.4.2](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.2) (April 4, 2018)
+* Fixed final case of duplicated instance insertion, caused by reconciled instances not being inserted into `RouteMap`.
+    * The reconciler is still not a perfect solution, especially if script instances get moved around without being destroyed. I don't think this can be fixed before a big refactor.
+
+## [0.4.1](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.1) (April 1, 2018)
+* Merged plugin repository into main Rojo repository for easier tracking.
+* Improved `RouteMap` object tracking; this should fix some cases of duplicated instances being synced into the tree.
+
+## [0.4.0](https://github.com/rojo-rbx/rojo/releases/tag/v0.4.0) (March 27, 2018)
+* Protocol version 1, which shifts more responsibility onto the server
+    * This is a **major breaking** change!
+    * The server now has a content of 'filter plugins', which transform data at various stages in the pipeline
+    * The server now exposes Roblox instance objects instead of file contents, which lines up with how `rojo pack` will work, and paves the way for more robust syncing.
+* Added `*.model.json` files, which let you embed small Roblox objects into your Rojo tree.
+* Improved error messages in some cases ([#46](https://github.com/rojo-rbx/rojo/issues/46))
+
+## [0.3.2](https://github.com/rojo-rbx/rojo/releases/tag/v0.3.2) (December 20, 2017)
+* Fixed `rojo serve` failing to correctly construct an absolute root path when passed as an argument
+* Fixed intense CPU usage when running `rojo serve`
+
+## [0.3.1](https://github.com/rojo-rbx/rojo/releases/tag/v0.3.1) (December 14, 2017)
+* Improved error reporting when invalid JSON is found in a `rojo.json` project
+    * These messages are passed on from Serde
+
+## [0.3.0](https://github.com/rojo-rbx/rojo/releases/tag/v0.3.0) (December 12, 2017)
+* Factored out the plugin into a separate repository
+* Fixed server when using a file as a partition
+    * Previously, trailing slashes were put on the end of a partition even if the read request was an empty string. This broke file reading on Windows when a partition pointed to a file instead of a directory!
+* Started running automatic tests on Travis CI (#9)
+
+## [0.2.3](https://github.com/rojo-rbx/rojo/releases/tag/v0.2.3) (December 4, 2017)
+* Plugin only release
+* Tightened `init` file rules to only match script files
+    * Previously, Rojo would sometimes pick up the wrong file when syncing
+
+## [0.2.2](https://github.com/rojo-rbx/rojo/releases/tag/v0.2.2) (December 1, 2017)
+* Plugin only release
+* Fixed broken reconciliation behavior with `init` files
+
+## [0.2.1](https://github.com/rojo-rbx/rojo/releases/tag/v0.2.1) (December 1, 2017)
+* Plugin only release
+* Changes default port to 8000
+
+## [0.2.0](https://github.com/rojo-rbx/rojo/releases/tag/v0.2.0) (December 1, 2017)
+* Support for `init.lua` like rbxfs and rbxpacker
+* More robust syncing with a new reconciler
+
+## [0.1.0](https://github.com/rojo-rbx/rojo/releases/tag/v0.1.0) (November 29, 2017)
+* Initial release, functionally very similar to [rbxfs](https://github.com/rojo-rbx/rbxfs)

+# Contributing to the Rojo Project
+Rojo is a big project and can always use more help! This guide covers all repositories underneath the [rojo-rbx organization on GitHub](https://github.com/rojo-rbx).
+
+Some of the repositories covered are:
+
+* https://github.com/rojo-rbx/rojo
+* https://github.com/rojo-rbx/rbx-dom
+* https://github.com/rojo-rbx/vscode-rojo
+* https://github.com/rojo-rbx/rbxlx-to-rojo
+
+## Code
+Code contributions are welcome for features and bugs that have been reported in the project's bug tracker. We want to make sure that no one wastes their time, so be sure to talk with maintainers about what changes would be accepted before doing any work!
+
+## Documentation
+Documentation impacts way more people than the individual lines of code we write.
+
+If you find any problems in documentation, including typos, bad grammar, misleading phrasing, or missing content, feel free to file issues and pull requests to fix them.
+
+## Bug Reports and Feature Requests
+Most of the tools around Rojo try to be clear when an issue is a bug. Even if they aren't, sometimes things don't work quite right.
+
+Sometimes there's something that Rojo doesn't do that it probably should.
+
+Please file issues and we'll try to help figure out what the best way forward is.
+
+## Pushing a Rojo Release
+The Rojo release process is pretty manual right now. If you need to do it, here's how:
+
+1. Bump server version in [`server/Cargo.toml`](server/Cargo.toml)
+2. Bump plugin version in [`plugin/src/Config.lua`](plugin/src/Config.lua)
+3. Run `cargo test` to update `Cargo.lock` and double-check tests
+4. Update [`CHANGELOG.md`](CHANGELOG.md)
+5. Commit!
+    * `git add . && git commit -m "Release vX.Y.Z"`
+6. Tag the commit with the version from `Cargo.toml` prepended with a v, like `v0.4.13`
+7. Build Windows release build of CLI
+    * `cargo build --release`
+7. Publish the CLI
+    * `cargo publish`
+8. Build and upload the plugin
+    * `rojo build plugin -o Rojo.rbxm`
+    * Upload `Rojo.rbxm` to Roblox.com, keep it for later
+9. Push commits and tags
+    * `git push && git push --tags`
+10. Copy GitHub release content from previous release
+    * Update the leading text with a summary about the release
+    * Paste the changelog notes (as-is!) from [`CHANGELOG.md`](CHANGELOG.md)
+    * Write a small summary of each major feature

+--------------------------------
+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or

+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+*  Covered Software is provided under this License on an "as is"       *
+*  basis, without warranty of any kind, either expressed, implied, or  *
+*  statutory, including, without limitation, warranties that the       *
+*  Covered Software is free of defects, merchantable, fit for a        *
+*  particular purpose or non-infringing. The entire risk as to the     *
+*  quality and performance of the Covered Software is with You.        *
+*  Should any Covered Software prove defective in any respect, You     *
+*  (not any Contributor) assume the cost of any necessary servicing,   *
+*  repair, or correction. This disclaimer of warranty constitutes an   *
+*  essential part of this License. No use of any Covered Software is   *
+*  authorized under this License except under this disclaimer.         *
+*                                                                      *

+*  Under no circumstances and under no legal theory, whether tort      *
+*  (including negligence), contract, or otherwise, shall any           *
+*  Contributor, or anyone who distributes Covered Software as          *
+*  permitted above, be liable to You for any direct, indirect,         *
+*  special, incidental, or consequential damages of any character      *
+*  including, without limitation, damages for lost profits, loss of    *
+*  goodwill, work stoppage, computer failure or malfunction, or any    *
+*  and all other commercial damages or losses, even if such party      *

+*  personal injury resulting from such party's negligence to the       *
+*  extent applicable law prohibits such limitation. Some               *
+*  jurisdictions do not allow the exclusion or limitation of           *
+*  incidental or consequential damages, so this exclusion and          *

+************************************************************************
+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or
+publish new versions of this License. Each version will be given a
+distinguishing version number.
+
+10.2. Effect of New Versions
+
+You may distribute the Covered Software under the terms of the version
+of the License under which You originally received the Covered Software,
+or under the terms of any subsequent version published by the license
+steward.
+
+10.3. Modified Versions
+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a
+modified version of this License if you rename the license and remove
+any references to the name of the license steward (except to note that
+such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+Licenses
+
+If You choose to distribute Source Code Form that is Incompatible With
+Secondary Licenses under the terms of this version of the License, the
+notice described in Exhibit B of this License must be attached.

-It's designed for power users who want to use the **best tools available** for building games, libraries, and plugins.
+<hr />
 
-This is the main Rojo repository, containing the binary server component. For the source for the Roblox plugin, [see the rojo-plugin repository](https://github.com/LPGhatguy/rojo-plugin).
+**Rojo** is a tool designed to enable Roblox developers to use professional-grade software engineering tools.
+
+With Rojo, it's possible to use industry-leading tools like **Visual Studio Code** and **Git**.
+
+Rojo is designed for power users who want to use the best tools available for building games, libraries, and plugins.
 
 ## Features
+Rojo enables:
 
-Rojo has a number of desirable features *right now*:
-
-* Work on scripts from the filesystem, in your favorite editor
-* Version your place, library, or plugin using Git or another VCS
+* Working on scripts and models from the filesystem, in your favorite editor
+* Versioning your game, library, or plugin using Git or another VCS
+* Streaming `rbxmx` and `rbxm` models into your game in real time
+* Packaging and deploying your project to Roblox.com from the command line
 
 Soon, Rojo will be able to:
 
-* Sync Roblox objects (including models) bi-directionally between the filesystem and Roblox Studio
-* Create installation scripts for libraries to be used in standalone places
-	* Similar to [rbxpacker](https://github.com/LPGhatguy/rbxpacker), another one of my projects
-* Add strongly-versioned dependencies to your project
+* Automatically convert your existing game to work with Rojo
+* Sync instances from Roblox Studio to the filesystem
+* Automatically manage your assets on Roblox.com, like images and sounds
+* Import custom instances like MoonScript code
 
-## Installation
-Rojo has two components:
-* The command line tool, written in Rust
-* The [Roblox Studio plugin](https://www.roblox.com/library/1211549683/Rojo), written in Lua
+## [Documentation](https://rojo.space/docs/latest)

-## Usage
-For more help, use `rojo help`.
+Pull requests are welcome!
 
-### New Project
-Just create a new folder and tell Rojo to initialize it!
-
-```sh
-mkdir my-new-project
-cd my-new-project
-
-rojo init
-```
-
-Rojo will create an empty project in the directory.
-
-The default project looks like this:
-
-```json
-{
-  "name": "my-new-project",
-  "servePort": 8000,
-  "partitions": {}
-}
-```
-
-### Start Dev Server
-To create a server that allows the Rojo Dev Plugin to access your project, use:
-
-```sh
-rojo serve
-```
-
-The tool will tell you whether it found an existing project. You should then be able to connect and use the project from within Roblox Studio!
-
-### Migrating an Existing Roblox Project
-**Coming soon!**
-
-### Syncing into Roblox
-In order to sync code into Roblox, you'll need to add one or more "partitions" to your configuration. A partition tells Rojo how to map directories to Roblox objects.
-
-Each entry in the partitions table has a unique name, a filesystem path, and the full name of the Roblox object to sync into.
-
-For example, if you want to map your `src` directory to an object named `My Cool Game` in `ReplicatedStorage`, you could use this configuration:
-
-```json
-{
-  "name": "rojo",
-  "servePort": 8000,
-  "partitions": {
-    "game": {
-      "path": "src",
-      "target": "ReplicatedStorage.My Cool Game"
-    }
-  }
-}
-```
-
-The `path` parameter is relative to the project file.
-
-The `target` starts at `game` and crawls down the tree. If any objects don't exist along the way, they'll be created as `Folder` instances.
-
-Run `rojo serve` in the directory containing this project, then press the "Sync In" or "Toggle Polling" buttons in the Roblox Studio plugin to move code into your game.
-
-### Sync Details
-The structure of files and folders on the filesystem are preserved when syncing into game.
-
-Creation of Roblox instances follows a simple set of rules. The first rule that matches the file name is chosen:
-
-| File Name      | Instance Type  | Notes                                     |
-| -------------- | -------------- | ----------------------------------------- |
-| `*.server.lua` | `Script`       | `Source` will contain the file's contents |
-| `*.client.lua` | `LocalScript`  | `Source` will contain the file's contents |
-| `*.lua`        | `ModuleScript` | `Source` will contain the file's contents |
-| `*`            | `StringValue`  | `Value` will contain the file's contents  |
-
-Any folders on the filesystem will turn into `Folder` objects unless they contain a file named `init.lua`, `init.server.lua`, or `init.client.lua`. Following the convention of Lua, those objects will instead be whatever the `init` file would turn into.
-
-For example, this file tree:
-
-* my-game
-	* init.client.lua
-	* foo.lua
-
-Will turn into this tree in Roblox:
-
-* `my-game` (`LocalScript` with source from `my-game/init.client.lua`)
-	* `foo` (`ModuleScript` with source from `my-game/foo.lua`)
-
-## Inspiration
-There are lots of other tools that sync scripts into Roblox, or otherwise work to improve the development flow outside of Roblox Studio.
-
-Here are a few, if you're looking for alternatives or supplements to Rojo:
-* [Studio Bridge by Vocksel](https://github.com/vocksel/studio-bridge)
-* [RbxRefresh by Osyris](https://github.com/osyrisrblx/RbxRefresh)
-* [RbxSync by evaera](https://github.com/evaera/RbxSync)
-* [CodeSync](https://github.com/MemoryPenguin/CodeSync) and [rbx-exteditor](https://github.com/MemoryPenguin/rbx-exteditor) by [MemoryPenguin](https://github.com/MemoryPenguin)
-* [rbxmk by Anaminus](https://github.com/anaminus/rbxmk)
-
-I also have a couple tools that Rojo intends to replace:
-* [rbxfs](https://github.com/LPGhatguy/rbxfs), which has been deprecated by Rojo
-* [rbxpacker](https://github.com/LPGhatguy/rbxpacker), which is still useful
+Rojo supports Rust 1.34.0 and newer. The minimum supported version of Rust is based on the latest versions of the dependencies that Rojo has.

+This is this installation guide for Rojo **0.5.x**.
+
+[TOC]
+
+## Overview
+Rojo has two components:
+
+* The command line interface (CLI)
+* The Roblox Studio plugin
+
+!!! info
+    It's important that your installed version of the plugin and CLI are compatible.
+
+    The plugin will show errors in the Roblox Studio output window if there is a version mismatch.
+
+## Visual Studio Code Extension
+If you use Visual Studio Code, you can install [the Rojo VS Code extension](https://marketplace.visualstudio.com/items?itemName=evaera.vscode-rojo), which will install both halves of Rojo for you. It even has a nifty UI to sync files and start/stop the Rojo server!
+
+## Installing the CLI
+
+### Installing from GitHub
+If you're on Windows, there are pre-built binaries available from Rojo's [GitHub Releases page](https://github.com/LPGhatguy/rojo/releases).
+
+The Rojo CLI must be run from the command line, like Terminal.app on MacOS or `cmd.exe` on Windows. It's recommended that you put the Rojo CLI executable on your `PATH` to make this easier.
+
+### Installing from Cargo
+If you have Rust installed, the easiest way to get Rojo is with Cargo!
+
+To install the latest 0.5.x release, use:
+
+```sh
+cargo install rojo
+```
+
+If you're upgrading from a previous version of Rojo, you may need to pass `--force` to tell Cargo to overwrite your existing version.
+
+## Installing the Plugin
+
+### Installing from GitHub
+The Rojo Roblox Studio plugin is available from Rojo's [GitHub Releases page](https://github.com/LPGhatguy/rojo/releases).
+
+Download the attached `rbxm` file and put it into your Roblox Studio plugins folder. You can find that folder by pressing **Plugins Folder** from your Plugins toolbar in Roblox Studio:
+
+!['Plugins Folder' button in Roblox Studio](../images/plugins-folder-in-studio.png)
+{: align="center" }
+
+### Installing from Roblox.com
+Visit [Rojo's Roblox.com Plugin page](https://www.roblox.com/library/1997686364) in Roblox Studio and press **Install**.

+Rojo underwent a large refactor during most of 2018 to enable a bunch of new features and lay groundwork for lots more in 2019. As such, Rojo **0.5.x** projects are not compatible with Rojo **0.4.x** projects.
+
+[TOC]
+
+## Supporting Both 0.4.x and 0.5.x
+Rojo 0.5.x uses a different name for its project format. While 0.4.x used `rojo.json`, 0.5.x uses `default.project.json`, which allows them to coexist.
+
+If you aren't sure about upgrading or want to upgrade gradually, it's possible to keep both files in the same project without causing problems.
+
+## Upgrading Your Project File
+Project files in 0.5.x are more explicit and flexible than they were in 0.4.x. Project files can now describe models and plugins in addition to places.
+
+This new project file format also guards against two of the biggest pitfalls when writing a config file:
+
+* Using a service as a partition target directly, which often wiped away extra instances
+* Defining two partitions that overlapped, which made Rojo act unpredictably
+
+The biggest change is that the `partitions` field has been replaced with a new field, `tree`, that describes the entire hierarchy of your project from the top-down.
+
+A project for 0.4.x that syncs from the `src` directory into `ReplicatedStorage.Source` would look like this:
+
+```json
+{
+    "name": "Rojo 0.4.x Example",
+    "partitions": {
+        "path": "src",
+        "target": "ReplicatedStorage.Source"
+    }
+}
+```
+
+In 0.5.x, the project format is more explicit:
+
+```json
+{
+    "name": "Rojo 0.5.x Example",
+    "tree": {
+        "$className": "DataModel",
+        "ReplicatedStorage": {
+            "$className": "ReplicatedStorage",
+            "Source": {
+                "$path": "src"
+            }
+        }
+    }
+}
+```
+
+For each object in the tree, we define *metadata* and *children*.
+
+Metadata begins with a dollar sign (`$`), like `$className`. This is so that children and metadata can coexist without creating too many nested layers.
+
+All other values are considered children, where the key is the instance's name, and the value is an object, repeating the process.
+
+## Migrating Unknown Files
+If you used Rojo to sync in files as `StringValue` objects, you'll need to make sure those files end with the `txt` extension to preserve this in Rojo 0.5.x.
+
+Unknown files are now ignored in Rojo instead of being converted to `StringValue` objects.
+
+## Migrating `init.model.json` files
+In Rojo 0.4.x, it's possible to create a file named `init.model.json` that lets you describe a model that becomes the container for all of the other files in the folder, just like `init.lua`.
+
+In Rojo 0.5.x, this feature has been replaced with `init.meta.json` files. See [Sync Details](../../reference/sync-details) for more information about these new files.

+[TOC]
+
+## Creating the Rojo Project
+To use Rojo to build a game, you'll need to create a new project file, which tells Rojo how to turn your files into a Roblox place.
+
+First, create a new folder to contain the files for your game and open up a new terminal inside of it, like cmd.exe or Bash.
+
+It's convenient to make the folder from the command line:
+
+```sh
+mkdir my-new-project
+cd my-new-project
+```
+
+Inside the folder, initialize a new Rojo project:
+
+```sh
+rojo init
+```
+
+Rojo will make a small project file in your directory, named `default.project.json`. It matches the "Baseplate" template from Roblox Studio, except that it'll take any files you put in a folder called `src` and put it into `ReplicatedStorage.Source`.
+
+Speaking of files, make sure to create a directory named `src` in this folder, or Rojo will be upset about missing files!
+
+```sh
+mkdir src
+```
+
+Let's also add a Lua file, `hello.lua` to the `src` folder, so that we can make this project our own.
+
+```sh
+echo 'return "Hello, Rojo!"' > src/hello.lua
+```
+
+## Building Your Place
+Now that we have a project, one thing we can do is build a Roblox place file for our project. This is a great way to get started with a project quickly with no fuss.
+
+All we have to do is call `rojo build`:
+
+```sh
+rojo build -o MyNewProject.rbxlx
+```
+
+If you open `MyNewProject.rbxlx` in Roblox Studio now, you should see a `Folder` named "Source" containing a `ModuleScript` under `ReplicatedStorage`.
+
+!!! info
+    To generate a binary place file instead, use `rbxl`. Note that support for binary model/place files (`rbxm` and `rbxl`) is very limited in Rojo presently.
+
+## Live-Syncing into Studio
+Building a place file is great for starting to work on a game, but for active iteration, you'll want something faster.
+
+In Roblox Studio, make sure the Rojo plugin is installed. If you need it, check out [the installation guide](../installation) to learn how to install it.
+
+To expose your project to the plugin, you'll need to start a new **live sync session** from the command line:
+
+```sh
+rojo serve
+```
+
+You should see output like this in your terminal:
+
+```sh
+$ rojo serve
+Rojo server listening on port 34872
+```
+
+Switch into Roblox Studio and press the **Connect** button on the Rojo plugin toolbar. A dialog should appear:
+
+![Rojo plugin connection dialog](../images/connection-dialog.png)
+{: class="feature-image" align="center" }
+
+If the port number doesn't match the output from the command line, change it, and then press **Connect**.
+
+If all went well, you should now be able to change files in the `src` directory and watch them sync into Roblox Studio in real time!
+
+## Uploading Your Place
+Aimed at teams that want serious levels of automation, Rojo can upload places to Roblox.com automatically.
+
+You'll need an existing game on Roblox.com as well as the `.ROBLOSECURITY` cookie of an account that has write access to that game.
+
+!!! warning
+    It's recommended that you set up a Roblox account dedicated to deploying your game instead of your personal account in case your security cookie is compromised.
+
+Generating and publishing your game is as simple as:
+
+```sh
+rojo upload --asset_id [PLACE ID] --cookie "[SECURITY COOKIE]"
+```
+
+An example project is available on GitHub that deploys to Roblox.com from GitHub and Travis-CI automatically: [https://github.com/LPGhatguy/roads](https://github.com/LPGhatguy/roads)

+This document aims to give a general overview of how Rojo works. It's intended for people who want to contribute to the project as well as anyone who's just curious how the tool works!
+
+[TOC]
+
+## CLI
+
+### RbxTree
+Rojo uses a library named [`rbx_tree`](https://github.com/LPGhatguy/rbx-tree) as its implementation of the Roblox DOM. It serves as a common format for serialization to all the formats Rojo supports!
+
+Rojo uses two related libraries to deserialize instances from Roblox's file formats, `rbx_xml` and `rbx_binary`.
+
+### In-Memory Filesystem (IMFS)
+Relevant source files:
+
+* [`server/src/imfs.rs`](https://github.com/LPGhatguy/rojo/blob/master/server/src/imfs.rs)
+* [`server/src/fs_watcher.rs`](https://github.com/LPGhatguy/rojo/blob/master/server/src/fs_watcher.rs)
+
+Rojo keeps an in-memory copy of all files that it needs reasons about. This enables taking fast, stateless, tear-tree snapshots of files to turn them into instances.
+
+Keeping an in-memory copy of file contents will also enable Rojo to debounce changes that are caused by Rojo itself. This'll happen when two-way sync finally happens.
+
+### Snapshot Reconciler
+Relevant source files:
+
+* [`server/src/snapshot_reconciler.rs`](https://github.com/LPGhatguy/rojo/blob/master/server/src/snapshot_reconciler.rs)
+* [`server/src/rbx_snapshot.rs`](https://github.com/LPGhatguy/rojo/blob/master/server/src/rbx_snapshot.rs)
+* [`server/src/rbx_session.rs`](https://github.com/LPGhatguy/rojo/blob/master/server/src/rbx_session.rs)
+
+To simplify incremental updates of instances, Rojo generates lightweight snapshots describing how files map to instances. This means that Rojo can treat file change events similarly to damage painting as opposed to trying to surgically update the correct instances.
+
+This approach reduces the number of desynchronization bugs, reduces the complexity of important pieces of the codebase, and makes writing plugins a lot easier.
+
+### HTTP API
+Relevant source files:
+
+* [`server/src/web.rs`](https://github.com/LPGhatguy/rojo/blob/master/server/src/web.rs)
+
+The Rojo live-sync server and Roblox Studio plugin communicate via HTTP.
+
+Requests sent from the plugin to the server are regular HTTP requests.
+
+Messages sent from the server to the plugin are delivered via HTTP long-polling. This is an approach that uses long-lived HTTP requests that restart on timeout. It's largely been replaced by WebSockets, but Roblox doesn't have support for them.

+Rojo is designed to be adopted incrementally. How much of your project Rojo manages is up to you!
+
+There are two primary categories of ways to use Rojo: *Fully Managed*, where everything is managed by Rojo, and *Partially Managed*, where Rojo only manages a slice of your project.
+
+## Fully Managed
+In a fully managed game project, Rojo controls every instance. A fully managed Rojo project can be built from scratch using `rojo build`.
+
+Fully managed projects are most practical for libraries, plugins, and simple games.
+
+Rojo's goal is to make it practical and easy for _every_ project to be fully managed, but we're not quite there yet!
+
+### Pros
+* Fully reproducible builds from scratch
+* Everything checked into version control
+
+### Cons
+* Without two-way sync, models have to be saved manually
+    * This can be done with the 'Save to File...' menu in Roblox Studio
+    * This will be solved by Two-Way Sync ([issue #164](https://github.com/LPGhatguy/rojo/issues/164))
+* Rojo can't manage everything yet
+    * Refs are currently broken ([issue #142](https://github.com/LPGhatguy/rojo/issues/142))
+
+## Partially Managed
+In a partially managed project, Rojo only handles a slice of the game. This could be as small as a couple scripts, or as large as everything except `Workspace`!
+
+The rest of the place's content can be versioned using Team Create or checked into source control.
+
+Partially managed projects are most practical for complicated games, or games that are migrating to use Rojo.
+
+### Pros
+* Easier to adopt gradually
+* Integrates with Team Create
+
+### Cons
+* Not everything is in version control, which makes merges tougher
+* Rojo can't live-sync instances like Terrain, MeshPart, or CSG operations yet
+    * Will be fixed with plugin escalation ([issue #169](https://github.com/LPGhatguy/rojo/issues/169))

+[TOC]
+
+## Project File
+Rojo projects are JSON files that have the `.project.json` extension. They have the following fields:
+
+* `name`: A string indicating the name of the project. This name is used when building the project into a model or place file.
+    * **Required**
+* `tree`: An [Instance Description](#instance-description) describing the root instance of the project.
+    * **Required**
+* `servePort`: The port that `rojo serve` should listen on. Passing `--port` will override this setting.
+    * **Optional**
+    * Default is `34872`
+* `servePlaceIds`: A list of place IDs that this project may be live-synced to. This feature can help prevent overwriting the wrong game with source from Rojo.
+    * **Optional**
+    * Default is `null`
+
+## Instance Description
+Instance Descriptions correspond one-to-one with the actual Roblox Instances in the project.
+
+* `$className`: The ClassName of the Instance being described.
+    * **Optional if `$path` is specified.**
+* `$path`: The path on the filesystem to pull files from into the project.
+    * **Optional if `$className` is specified.**
+    * Paths are relative to the folder containing the project file.
+* `$properties`: Properties to apply to the instance. Values should be [Instance Property Values](#instance-property-value).
+    * **Optional**
+* `$ignoreUnknownInstances`: Whether instances that Rojo doesn't know about should be deleted.
+    * **Optional**
+    * Default is `false` if `$path` is specified, otherwise `true`.
+
+All other fields in an Instance Description are turned into instances whose name is the key. These values should also be Instance Descriptions!
+
+Instance Descriptions are fairly verbose and strict. In the future, it'll be possible for Rojo to [infer class names for known services like `Workspace`](https://github.com/LPGhatguy/rojo/issues/179).
+
+## Instance Property Value
+There are two kinds of property values on instances, **implicit** and **explicit**.
+
+In the vast majority of cases, you should be able to use **implicit** property values. To use them, just use a value that's the same shape as the type that the property has:
+
+```json
+"MyPart": {
+    "$className": "Part",
+    "$properties": {
+        "Size": [3, 5, 3],
+        "Color": [0.5, 0, 0.5],
+        "Anchored": true,
+        "Material": "Granite"
+    }
+}
+```
+
+`Vector3` and `Color3` properties can just be arrays of numbers, as can types like `Vector2`, `CFrame`, and more!
+
+Enums can be set to a string containing the enum variant. Rojo will raise an error if the string isn't a valid variant for the enum.
+
+There are some cases where this syntax for assigning properties _doesn't_ work. In these cases, Rojo requires you to use the **explicit** property syntax.
+
+Some reasons why you might need to use an **explicit** property:
+
+* Using exotic property types like `BinaryString`
+* Using properties added to Roblox recently that Rojo doesn't know about yet
+
+The shape of explicit property values is defined by the [rbx-dom](https://github.com/LPGhatguy/rbx-dom) library, so it uses slightly different conventions than the rest of Rojo.
+
+Each value should be an object with the following required fields:
+
+* `Type`: The type of property to represent.
+    * [Supported types can be found here](https://github.com/LPGhatguy/rbx-tree#property-type-coverage).
+* `Value`: The value of the property.
+    * The shape of this field depends on which property type is being used. `Vector3` and `Color3` values are both represented as a list of numbers, while `BinaryString` expects a base64-encoded string, for example.
+
+Here's the same object, but with explicit properties:
+
+```json
+"MyPart": {
+    "$className": "Part",
+    "$properties": {
+        "Size": {
+            "Type": "Vector3",
+            "Value": [3, 5, 3]
+        },
+        "Color": {
+            "Type": "Color3",
+            "Value": [0.5, 0, 0.5]
+        },
+        "Anchored": {
+            "Type": "Bool",
+            "Value": true
+        },
+        "Material": {
+            "Type": "Enum",
+            "Value": 832
+        }
+    }
+}
+```
+
+## Example Projects
+This project bundles up everything in the `src` directory. It'd be suitable for making a plugin or model:
+
+```json
+{
+    "name": "AwesomeLibrary",
+    "tree": {
+        "$path": "src"
+    }
+}
+```
+
+This project describes the layout you might use if you were making the next hit simulator game, *Sisyphus Simulator*:
+
+```json
+{
+    "name": "Sisyphus Simulator",
+    "tree": {
+        "$className": "DataModel",
+
+        "HttpService": {
+            "$className": "HttpService",
+            "$properties": {
+                "HttpEnabled": true
+            }
+        },
+
+        "ReplicatedStorage": {
+            "$className": "ReplicatedStorage",
+            "$path": "src/ReplicatedStorage"
+        },
+
+        "StarterPlayer": {
+            "$className": "StarterPlayer",
+
+            "StarterPlayerScripts": {
+                "$className": "StarterPlayerScripts",
+                "$path": "src/StarterPlayerScripts"
+            }
+        },
+
+        "Workspace": {
+            "$className": "Workspace",
+            "$properties": {
+                "Gravity": 67.3
+            },

+            }

+This page aims to describe how Rojo turns files on the filesystem into Roblox objects.
+
+[TOC]
+
+## Overview
+| File Name      | Instance Type             |
+| -------------- | ------------------------- |
+| any directory  | `Folder`                  |
+| `*.server.lua` | `Script`                  |
+| `*.client.lua` | `LocalScript`             |
+| `*.lua`        | `ModuleScript`            |
+| `*.csv`        | `LocalizationTable`       |
+| `*.txt`        | `StringValue`             |
+| `*.model.json` | Any                       |
+| `*.rbxm`       | Any                       |
+| `*.rbxmx`      | Any                       |
+| `*.meta.json`  | Modifies another instance |
+
+## Limitations
+Not all property types can be synced by Rojo in real-time due to limitations of the Roblox Studio plugin API. In these cases, you can usually generate a place file and open it when you start working on a project.
+
+Some common cases you might hit are:
+
+* Binary data (Terrain, CSG, CollectionService tags)
+* `MeshPart.MeshId`
+* `HttpService.HttpEnabled`
+
+For a list of all property types that Rojo can reason about, both when live-syncing and when building place files, look at [rbx-dom's type coverage chart](https://github.com/rojo-rbx/rbx-dom#property-type-coverage).
+
+This limitation may be solved by [issue #205](https://github.com/rojo-rbx/rojo/issues/205) in the future.
+
+## Folders
+Any directory on the filesystem will turn into a `Folder` instance unless it contains an 'init' script, described below.
+
+## Scripts
+The default script type in Rojo projects is `ModuleScript`, since most scripts in well-structued Roblox projects will be modules.
+
+If a directory contains a file named `init.server.lua`, `init.client.lua`, or `init.lua`, that folder will be transformed into a `*Script` instance with the contents of the 'init' file. This can be used to create scripts inside of scripts.
+
+For example, these files:
+
+![Tree of files on disk](../images/sync-example-files.svg)
+{: align="center" }
+
+Will turn into these instances in Roblox:
+
+![Tree of instances in Roblox](../images/sync-example-instances.svg)
+{: align="center" }
+
+## Localization Tables
+Any CSV files are transformed into `LocalizationTable` instances. Rojo expects these files to follow the same format that Roblox does when importing and exporting localization information.
+
+## Plain Text Files
+Plain text files (`.txt`) files are transformed into `StringValue` instances. This is useful for bringing in text data that can be read by scripts at runtime.
+
+## JSON Models
+Files ending in `.model.json` can be used to describe simple models. They're designed to be hand-written and are useful for instances like `RemoteEvent`.
+
+A JSON model describing a folder containing a `Part` and a `RemoteEvent` could be described as:
+
+```json
+{
+    "Name": "My Cool Model",
+    "ClassName": "Folder",
+    "Children": [
+        {
+            "Name": "RootPart",
+            "ClassName": "Part",
+            "Properties": {
+                "Size": {
+                    "Type": "Vector3",
+                    "Value": [4, 4, 4]
+                }
+            }
+        },
+        {
+            "Name": "SendMoney",
+            "ClassName": "RemoteEvent"
+        }
+    ]
+}
+```
+
+It would turn into instances in this shape:
+
+![Tree of instances in Roblox](../images/sync-example-json-model.svg)
+{: align="center" }
+
+!!! warning
+    Starting in Rojo 0.5.0 (stable), the `Name` field is no longer required. The name of the top-level instance in a JSON model is now based on its file name, and the `Name` field is now ignored.
+
+    Rojo will emit a warning if the `Name` field is specified and does not match the file's name.
+
+## Binary and XML Models
+Rojo supports both binary (`.rbxm`) and XML (`.rbxmx`) models generated by Roblox Studio or another tool.
+
+Support for the `rbxmx` is very good, while support for `rbxm` is still very early, buggy, and lacking features.
+
+For a rundown of supported types, check out [rbx-dom's type coverage chart](https://github.com/rojo-rbx/rbx-dom#property-type-coverage).
+
+## Meta Files
+New in Rojo 0.5.0-alpha.12 are meta files, named `.meta.json`.
+
+Meta files allow attaching extra Rojo data to models defined in other formats, like Roblox's `rbxm` and `rbxmx` model formats, or even Lua scripts.
+
+This can be used to set Rojo-specific settings like `ignoreUnknownInstances`, or can be used to set properties like `Disabled` on a script.
+
+Meta files can contain:
+
+* `className`: Changes the `className` of a containing `Folder` into something else.
+    * Usable only in `init.meta.json` files
+* `properties`: A map of properties to set on the instance, just like projects
+    * Usable on anything except `.rbxmx`, `.rbxm`, and `.model.json` files, which already have properties
+* `ignoreUnknownInstances`: Works just like `$ignoreUnknownInstances` in project files
+
+### Meta Files to set Rojo metadata
+Sometimes it's useful to apply properties like `ignoreUnknownInstances` on instances that are defined on the filesystem instead of within the project itself.
+
+If your project has `hello.txt` and there are instances underneath it that you want Rojo to ignore when live-syncing, you could create `hello.meta.json` with:
+
+```json
+{
+    "ignoreUnknownInstances": true
+}
+```
+
+### Meta Files for Disabled Scripts
+Meta files can be used to set properties on `Script` instances, like `Disabled`.
+
+If your project has `foo.server.lua` and you want to make sure it would be disabled, you could create a `foo.meta.json` next to it with:
+
+```json
+{
+    "properties": {
+        "Disabled": true
+    }
+}
+```
+
+### Meta Files for Tools
+If you wanted to represent a tool containing a script and a model for its handle, create a directory with an `init.meta.json` file in it:
+
+```json
+{
+    "className": "Tool",
+    "properties": {
+        "Grip": [
+            0, 0, 0,
+            1, 0, 0,
+            0, 1, 0,
+            0, 0, 1
+        ]
+    }
+}
+```
+
+Instead of a `Folder` instance, you'll end up with a `Tool` instance with the `Grip` property set!

+There are a number of existing plugins for Roblox that move code from the filesystem into Roblox.
+
+Besides Rojo, you might consider:
+
+* [rbxmk by Anaminus](https://github.com/anaminus/rbxmk)
+* [Rofresh by Osyris](https://github.com/osyrisrblx/rofresh)
+* [RbxRefresh by Osyris](https://github.com/osyrisrblx/RbxRefresh)
+* [Studio Bridge by Vocksel](https://github.com/vocksel/studio-bridge)
+* [Elixir by Vocksel](https://github.com/vocksel/elixir)
+* [RbxSync by evaera](https://github.com/evaera/RbxSync)
+* [CodeSync by MemoryPenguin](https://github.com/MemoryPenguin/CodeSync)
+* [rbx-exteditor by MemoryPenguin](https://github.com/MemoryPenguin/rbx-exteditor)
+
+So why did I build Rojo?
+
+Each of these tools solves what is essentially the same problem from a few different angles. The goal of Rojo is to take all of the lessons and ideas learned from these projects and build a tool that can solve this problem for good.
+
+Additionally:
+
+* I think that this tool needs to be built in a compiled language without a runtime, for easy distribution and good performance.
+* I think that the conventions promoted by other sync plugins (`.module.lua` for modules, as well a single sync point) are sub-optimal.
+* I think that I have a good enough understanding of the problem to build something robust.
+* I think that Rojo should be able to do more than just sync code.

+Adding a tool like Rojo to your Roblox workflow can be daunting, but it comes with some key advantages.
+
+[TOC]
+
+## Rojo at RDC 2019
+Nathan Riemer (Kampfkarren) gave a talk at RDC 2019 talking about some of the benefits of using a tool like Rojo.
+
+<iframe style="margin: 0 auto; max-width: 100%" width="560" height="315" src="https://www.youtube-nocookie.com/embed/czlvzEyhaBc" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
+
+## External Text Editors
+Rojo opens the door to use the absolute best text editors in the world and their rich plugin ecosystems.
+
+Some very popular editors include [Visual Studio Code](https://code.visualstudio.com) and [Sublime Text](https://www.sublimetext.com).
+
+These advanced text editors have features like multi-cursor editing, goto symbol, multi-file regex find and replace, bookmarks and much more.
+
+Many Rojo VS Code users also use extensions like:
+
+* [vscode-rbxlua](https://marketplace.visualstudio.com/items?itemName=AmaranthineCodices.vscode-rbxlua)
+* [Roblox Lua Autocompletes](https://marketplace.visualstudio.com/items?itemName=Kampfkarren.roblox-lua-autofills)
+* [TabNine](https://tabnine.com)
+
+## Version Control
+By building your game (or just the scripts) as individual files on the filesystem, it becomes easy to start using professional-grade version control tools like [Git](https://git-scm.com) and [GitHub](https://github.com).
+
+Hundreds of thousands of companies and individual developers use Git to version their software projects. With Rojo, Roblox developers can take advantage of the best collaboration tool around.
+
+Using a repository hosting service like GitHub or GitLab brings powerful features to Roblox developers like code reviews and issue tracking that professional engineers can't live without.
+
+## TypeScript
+TypeScript enables static type safety, which helps prevent typos and adds unparalleled autocompletion. It also brings features like arrow functions, object destructuring, functional programming methods, and more!
+
+With Rojo, you can use [roblox-ts](https://roblox-ts.github.io) to compile TypeScript to Lua and take advantage of a huge ecosystem of TypeScript tooling.
+
+It's also possible to use other languages that compile to Lua like [MoonScript](https://moonscript.org) and [Haxe](https://haxe.org).
+
+## Other Tools
+There are decades of excellent tools available that operate on files. With Rojo, it's possible to take advantage of any of them!
+
+Popular tools include:
+
+* [luacheck](https://github.com/mpeterv/luacheck), a static analysis tool to help you write better Lua
+* [ripgrep](https://github.com/BurntSushi/ripgrep), an extremely fast code search tool
+* [Tokei](https://github.com/XAMPPRocky/tokei), a tool for statistics like lines of code
