 # Rojo Changelog
 
-## [Unreleased]
+## Unreleased Changes for 0.6.x
+* Added basic settings panel to plugin, with two settings:
+    * "Open Scripts Externally": When enabled, opening a script in Studio will instead open it in your default text editor.
+    * "Two-Way Sync": When enabled, Rojo will attempt to save changes to your place back to the filesystem. **Very early feature, very broken, beware!**
+* Added `--color` option to force-enable or force-disable color in Rojo's output.
+* The server half of **experimental** two-way sync is now enabled by default.
+* Increased default logging verbosity in commands like `rojo build`.
 
-## [0.5.0 Alpha 5](https://github.com/LPGhatguy/rojo/releases/tag/v0.5.0-alpha.5) (March 1, 2019)
+## [0.6.0 Alpha 3](https://github.com/rojo-rbx/rojo/releases/tag/v0.6.0-alpha.3) (March 13, 2020)
+* Added `--watch` argument to `rojo build`. ([#284](https://github.com/rojo-rbx/rojo/pull/284))
+* Added dark theme support to plugin. ([#241](https://github.com/rojo-rbx/rojo/issues/241))
+* Added a revamped `rojo init` command, which will now create more complete projects.
+* Added the `rojo doc` command, which opens Rojo's documentation in your browser.
+* Fixed many crashes from malformed projects and filesystem edge cases in `rojo serve`.
+* Simplified filesystem access code dramatically.
+* Improved error reporting and logging across the board.
+    * Log messages have a less noisy prefix.
+    * Any thread panicking now causes Rojo to abort instead of existing as a zombie.
+    * Errors now have a list of causes, helping make many errors more clear.
+
+## [0.6.0 Alpha 2](https://github.com/rojo-rbx/rojo/releases/tag/v0.6.0-alpha.2) (March 6, 2020)
+* Fixed `rojo upload` command always uploading models.
+* Removed `--kind` parameter to `rojo upload`; Rojo now automatically uploads the correct kind of asset based on your project file.
+
+## [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 `rojo init` giving unexpected results by upgrading to `rbx_dom_weak` 1.1.0
+* 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

 * 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

 * 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.

+## [0.4.0](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.

 * 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)

+# 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!
+
+You'll want these tools to work on Rojo:
+
+* Latest stable Rust compiler
+* Latest stable [Rojo](https://github.com/rojo-rbx/rojo)
+* Latest stable [Remodel](https://github.com/rojo-rbx/remodel)
+* Latest stable [run-in-roblox](https://github.com/rojo-rbx/run-in-roblox)
+
+## 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 [`Cargo.toml`](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. 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
+    * Attach release artifacts from GitHub Actions for each platform

-## [Documentation](https://lpghatguy.github.io/rojo)
-You can also view the documentation by browsing the [docs](https://github.com/LPGhatguy/rojo/tree/master/docs) folder of the repository, but because it uses a number of Markdown extensions, it may not be very readable.
-
-## Inspiration and Alternatives
-There are lots of other tools that sync scripts into Roblox or provide other tools for working with Roblox places.
-
-Here are a few, if you're looking for alternatives or supplements to Rojo:

-* [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)
-
-If you use a plugin that _isn't_ Rojo for syncing code, open an issue and let me know why! I'd like Rojo to be the end-all tool so that people stop reinventing solutions to this problem.

+# Rojo as a C Library
+This is an experiment to expose a C API for Rojo that would be suitable for embedding it into an existing C/C++ application.
+
+I'm hoping to expand it to drop the HTTP layer and communicate through a channel, which could make it feasible to embed into an existing Roblox IDE with minimal changes or additional code.
+
+## Building
+This project is currently not built by default and could break/disappear at any time.
+
+```bash
+cargo build -p clibrojo
+```
+
+On Windows, Cargo will generate a `clibrojo.dll` and associated `.lib` file. Link these into your project.
+
+To generate the associated C header file to include in the project, use [cbindgen](https://github.com/eqrion/cbindgen):
+
+```bash
+cbindgen --crate clibrojo --output include/rojo.h
+```

-[TOC]
-
-## Creating the Rojo Project
-
-To use Rojo to build a place, you'll need to create a new project file, which tells Rojo how your project is structured on-disk and in Roblox.
-
-Create a new folder, then run `rojo init` inside that folder to initialize an empty project.
-
-```sh
-mkdir my-new-project
-cd my-new-project
-
-rojo init
-```
-
-Rojo will make a small project file in your directory, named `default.project.json`. It'll make sure that any code in the directory `src` will get put into `ReplicatedStorage.Source`.
-
-Speaking of, let's make sure we create a directory named `src`, and maybe a Lua file inside of it:
-
-```sh
-mkdir src
-echo 'print("Hello, world!")' > 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.rbxl
-```
-
-If you open `MyNewProject.rbxl` in Roblox Studio now, you should see a `Folder` containing a `ModuleScript` under `ReplicatedStorage`!
-
-!!! info
-    To generate an XML place file instead, like if you're checking the place file into version control, just use `rbxlx` as the extension on the output file instead.
-
-## Live-Syncing into Studio
-Building a place file is great for the initial build, but for actively working on your place, you'll want something quicker.
-
-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 _serve_ it from the command line:
-
-```sh
-rojo serve
-```
-
-This will start up a web server that tells Roblox Studio what instances are in your project and sends notifications if any of them change.
-
-Note the port number, then switch into Roblox Studio and press the Rojo **Connect** button in the plugins tab. Type in the port number, if necessary, and press **Start**.
-
-If everything 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 place on Roblox.com as well as the `.ROBLOSECURITY` cookie of an account that has write access to that place.
-
-!!! warning
-    It's recommended that you set up a Roblox account dedicated to deploying your place instead of your personal account in case your security cookie is compromised.
-
-Generating and uploading your place file is as simple as:
-
-```sh
-rojo upload --asset_id [PLACE ID] --cookie "[SECURITY COOKIE]"
-```

-## 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.
-
-## 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 0.5.0 alpha, use:
-
-```sh
-cargo install rojo --version 0.5.0-alpha.5
-```
-
-## Installing the Plugin
-
-### Installing from GitHub
-The Rojo Roblox Studio plugin is available 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/Rojo-0-5-0-alpha-3) in Roblox Studio and press **Install**.
-
-## Visual Studio Code Extension
-If you use Visual Studio Code on Windows, you can install [Evaera's unofficial Rojo 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 add partitions and start/stop the Rojo server!

-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 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.

-## Project File
-
-Rojo projects are JSON files that have the `.project.json` extension. They have these fields:
-
-* `name`: A string indicating the name of the project.
-    * This is only used for diagnostics.
-* `tree`: An [Instance Description](#instance-description) describing the root instance of the project.
-
-## Instance Description
-Instance Descriptions correspond one-to-one with the actual Roblox Instances in the project. They can be specified directly in the project file or be pulled from the filesystem.
-
-* `$className`: The ClassName of the Instance being described.
-    * Optional if `$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 `$path` is specified, otherwise `true`.
-
-All other fields in an Instance Description are turned into instances whose name is the key. These values should also be Instance Descriptions!
-
-Instance Descriptions are fairly verbose and strict. In the future, it'll be possible for Rojo to infer class names for known services like `Workspace`.
-
-## Instance Property Value
-The shape of Instance Property Values is defined by the [rbx_tree](https://github.com/LPGhatguy/rbx-tree) library, so it uses slightly different conventions than the rest of Rojo.
-
-Each value should be an object with the following required fields:
-
-* `Type`: The type of property to represent.
-    * [Supported types can be found here](https://github.com/LPGhatguy/rbx-tree#property-type-coverage).
-* `Value`: The value of the property.
-    * The shape of this field depends on which property type is being used. `Vector3` and `Color3` values are both represented as a list of numbers, for example.
-
-Instance Property Values are intentionally very strict. Rojo will eventually be able to infer types for you!
-
-## Example Projects
-This project bundles up everything in the `src` directory. It'd be suitable for making a plugin or model:
-
-```json
-{
-    "name": "AwesomeLibrary",
-    "tree": {
-        "$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",

-                }
-            }
-        },
-

-            "$className": "ReplicatedStorage",

-        "Workspace": {

-            "$properties": {
-                "Gravity": {

-## 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                 |
-
-## 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_tree's type coverage chart](https://github.com/LPGhatguy/rbx-tree#property-type-coverage).
-
-## 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": {

-## Binary and XML Models
-Rojo supports both binary (`.rbxm`) and XML (`.rbxmx`) models generated by Roblox Studio or another tool.
-
-Not all property types are supported for all formats!
-
-For a rundown of supported types, check out [rbx_tree's type coverage chart](https://github.com/LPGhatguy/rbx-tree#property-type-coverage).

-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)

-* [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.

+	This library describes a formatting mechanism akin to Rust's std::fmt.
+
+	It has a couple building blocks:
+
+	* A new syntax for formatting strings, taken verbatim from Rust. It'd also
+	  be possible to use printf-style formatting specifiers to integrate with
+	  the existing string.format utility.
+
+	* An equivalent to Rust's `Display` trait. We're mapping the semantics of
+	  tostring and the __tostring metamethod onto this trait. A lot of types
+	  should already have __tostring implementations, too!
+
+	* An equivalent to Rust's `Debug` trait. This library Lua-ifies that idea by
+	  inventing a new metamethod, `__fmtDebug`. We pass along the "extended
+	  form" attribute which is the equivalent of the "alternate mode" in Rust's
+	  Debug trait since it's the author's opinion that treating it as a
+	  verbosity flag is semantically accurate.
