-*No changes*
+* *No changes*
+
+## 0.4.13 (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 (June 21, 2018)
+* Fixed obscure assertion failure when renaming or deleting files ([#78](https://github.com/LPGhatguy/rojo/issues/78))
+* Added a `PluginAction` for the sync in command, which should help with some automation scripts ([#80](https://github.com/LPGhatguy/rojo/pull/80))
+
+## 0.4.11 (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 (June 2, 2018)
+* Added support for `init.model.json` files, which enable versioning `Tool` instances (among other things) with Rojo. ([#66](https://github.com/LPGhatguy/rojo/issues/66))
+* Fixed obscure error when syncing into an invalid service.
+* Fixed multiple sync processes occurring when a server ID mismatch is detected.
+
+## 0.4.9 (May 26, 2018)
+* Fixed warning when renaming or removing files that would sometimes corrupt the instance cache ([#72](https://github.com/LPGhatguy/rojo/pull/72))
+* JSON models are no longer as strict -- `Children` and `Properties` are now optional.
+
+## 0.4.8 (May 26, 2018)
+* Hotfix to prevent errors from being thrown when objects managed by Rojo are deleted
+
+## 0.4.7 (May 25, 2018)
+* Added icons to the Rojo plugin, made by [@Vorlias](https://github.com/Vorlias)! ([#70](https://github.com/LPGhatguy/rojo/pull/70))

+* 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 (May 1, 2018)
+* Rojo messages are now prefixed with `Rojo: ` to make them stand out in the output more.
+* Fixed server to notice file changes *much* more quickly. (200ms vs 1000ms)
+* Server now lists name of project when starting up.
+* Rojo now throws an error if no project file is found. ([#63](https://github.com/LPGhatguy/rojo/issues/63))
+* Fixed multiple sync operations occuring at the same time. ([#61](https://github.com/LPGhatguy/rojo/issues/61))
+* Partitions targeting files directly now work as expected. ([#57](https://github.com/LPGhatguy/rojo/issues/57))

+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

+    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 free of defects, merchantable, fit for a        *

+
+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

-## Server Usage
-For more help, use `rojo help`.
-
-### New Project
-Create a new folder, then use `rojo init` inside that folder to initialize an empty project:
-
-```sh
-mkdir my-new-project
-cd my-new-project
-
-rojo init
-```
-
-Rojo will create an empty project file named `rojo.json` in the directory.
-
-The default project file is:
-
-```json
-{
-  "name": "my-new-project",
-  "servePort": 8000,
-  "partitions": {}
-}
-```
-
-### Start Dev Server
-To start the Rojo dev server, 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
-[Bi-directional script syncing](https://github.com/LPGhatguy/rojo/issues/5) is on the roadmap for Rojo this year, but isn't implemented.
-
-In the mean-time, manually migrating scripts is probably the best route forward.
-
-### 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 on your filesystem to Roblox objects.
-
-Each entry in the `partitions` map 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` parameter is a path to a Roblox object to link the partition to, starting at `game`. If any objects don't exist along the way, Rojo will try to create them.
-
-**Any objects in a partition may be wiped away by Rojo after syncing! If this is not desired, use multiple, smaller partitions.**
-
-Run `rojo serve` in the directory containing this project, then press the "Sync In" or "Toggle Polling" buttons in the Roblox Studio plugin to sync into your game.
-
-### Sync Details
-The structure of files and diectories 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 |
-| `*.model.json` | *Varies*       | See the example below                     |
-| `*`            | `StringValue`  | `Value` will contain the file's contents  |
-
-Any directories on the filesystem will turn into `Folder` objects.
-
-Any directory containing one of these files will instead be a `ModuleScript`, `Script`, `LocalScript` containing the directory's contents:
-
-* `init.lua`
-* `init.server.lua`
-* `init.client.lua`
-
-For example, this file tree:
-
-* my-game
-	* init.client.lua
-	* foo.lua
-
-Will turn into these instances in Roblox:
-
-* `my-game` (`LocalScript` with source from `my-game/init.client.lua`)
-	* `foo` (`ModuleScript` with source from `my-game/foo.lua`)
-
-`*.model.json` files are a way to represent simple Roblox instances on the filesystem until `rbxmx` and `rbxlx` support is implemented in Rojo.
-
-This feature is intended for small instances, like `RemoteEvent` or `*Value` objects.
-
-JSON Model files are strict, with every property being required. They look like this:
-
-```json
-{
-  "Name": "hello",
-  "ClassName": "Model",
-  "Children": [
-    {
-      "Name": "Some Part",
-      "ClassName": "Part",
-      "Children": [],
-      "Properties": {}
-    },
-    {
-      "Name": "Some StringValue",
-      "ClassName": "StringValue",
-      "Children": [],
-      "Properties": {
-        "Value": {
-          "Type": "String",
-          "Value": "Hello, world!"
-        }
-      }
-    }
-  ],
-  "Properties": {}
-}
-```

+# Creating a Project
+To use Rojo, you'll need to create a new project file, which tells Rojo what your project is, and how to load it into Roblox Studio.
+
+## New Project
+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 create an empty project file named `rojo.json` in the directory.
+
+The default configuration doesn't do anything. We need to tell Rojo where our code is on the filesystem, and where we want to put it in the Roblox tree.
+
+To do that, open up `rojo.json` and add an entry to the `partitions` table:
+
+```json
+{
+    "name": "your-project-name-here",
+    "servePort": 8000,
+    "partitions": {
+        "src": {
+            "path": "src",
+            "target": "ReplicatedStorage.Project"
+        }
+    }
+}
+```
+
+!!! warning
+    Make sure that the `src` directory exists in your project, or Rojo will throw an error!
+
+!!! warning
+    Any objects contained in the `target` of a partition will be destroyed by Rojo if not found on the filesystem!
+
+A Rojo project has one or more *partitions*. Partitions define how code should be transferred between the filesystem and Roblox by mapping directories and files to Roblox objects.
+
+Each partition has:
+
+* A name (the key in the `partitions` object), which is used for debugging
+* `path`, the location on the filesystem relative to `rojo.json`
+* `target`, the location in Roblox relative to `game`
+
+## Syncing into Studio
+
+Once you've added your partition to the project file, you can start the Rojo dev server by running a command in your project's directory:
+
+```sh
+rojo serve
+```
+
+If your project is in the right place, Rojo will let you know that it was found and start an HTTP server that the plugin can connect to.
+
+In Roblox Studio, open the plugins tab and find Rojo's buttons.
+
+![Location of Rojo's plugin buttons in Roblox Studio](/images/plugin-buttons.png)
+{: align="center" }
+
+Press **Test Connection** to verify that the plugin can communicate with the dev server. Watch the Output panel for the results.
+
+!!! info
+    If you see an error message, return to the previous steps and make sure that the Rojo dev server is running.
+
+    ![Rojo error in Roblox Studio Output](/images/connection-error.png)
+    {: align="center" }
+
+After your connection was successful, press **Sync In** to move code from the filesystem into Studio, or use **Toggle Polling** to have Rojo automatically sync in changes as they happen.
+
+## Importing an Existing Project
+Rojo will eventually support importing an existing Roblox project onto the filesystem for use with Rojo.
+
+Rojo doesn't currently support converting an existing project or syncing files from Roblox Studio onto the filesystem. In the mean time, you can manually copy your files into the structure that Rojo expects.
+
+Up-to-date information will be available on [issue #5](https://github.com/LPGhatguy/rojo/issues/5) as this is worked on.

+* The server, a binary written in Rust
+* The plugin, a Roblox Studio plugin written in Lua
+
+It's important that the plugin and server are compatible. The plugin will show errors in the Roblox Studio Output window if there is a version mismatch.
+
+## Installing the Server
+To install the server, either:
+
+* If you have Rust installed, use `cargo install rojo`
+* Or, download a pre-built Windows binary from [the GitHub releases page](https://github.com/LPGhatguy/rojo/releases)
+
+**The Rojo binary must be run from the command line, like Terminal on MacOS or `cmd.exe` on Windows. It's recommended that you put the Rojo binary on your `PATH` to make this easier.**
+
+## Installing the Plugin
+To install the plugin, either:
+
+* Install the plugin from the [Roblox plugin page](https://www.roblox.com/library/1211549683/Rojo).
+  * This gives you less control over what version you install -- you will always have the latest version.
+* Or, download the latest release from [the GitHub releases section](https://github.com/LPGhatguy/rojo/releases) and install it into your Roblox plugins folder
+  * You can open this folder by clicking the "Plugins Folder" button from the Plugins toolbar in Roblox Studio
+
+## 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!

+# Sync Details
+This page aims to describe how Rojo turns files on the filesystem into Roblox objects.
+
+## Folders
+Any directory on the filesystem will turn into a `Folder` instance in Roblox, unless that folder matches the name of a service or other existing instance. In those cases, that instance will be preserved.
+
+## Scripts
+Rojo can represent `ModuleScript`, `Script`, and `LocalScript` objects. The default script type is `ModuleScript`, since most scripts in well-structued Roblox projects will be modules.
+
+| File Name      | Instance Type  |
+| -------------- | -------------- |
+| `*.server.lua` | `Script`       |
+| `*.client.lua` | `LocalScript`  |
+| `*.lua`        | `ModuleScript` |
+
+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 conents of the `init` file. This can be used to create scripts inside of scripts.
+
+For example, this file tree:
+
+* my-game
+    * init.client.lua
+    * foo.lua
+
+Will turn into these instances in Roblox:
+
+![Example of Roblox instances](/images/sync-example.png)
+
+## Models
+Rojo supports a JSON model format for representing simple models. It's designed for instance types like `BindableEvent` or `Value` objects, and is not suitable for larger models.
+
+Rojo JSON models are stored in `.model.json` files.
+
+Starting in Rojo version **0.4.10**, model files named `init.model.json` that are located in folders will replace that folder, much like Rojo's `init.lua` support. This can be useful to version instances like `Tool` that tend to contain several instances as well as one or more scripts.
+
+!!! info
+    In the future, Rojo will support `.rbxmx` models. See [issue #7](https://github.com/LPGhatguy/rojo/issues/7) for more details and updates on this feature.
+
+!!! warning
+    Prior to Rojo version **0.4.9**, the `Properties` and `Children` properties are required on all instances in JSON models!
+
+JSON model files are fairly strict; any syntax errors will cause the model to fail to sync! They look like this:
+
+`hello.model.json`
+```json
+{
+    "Name": "hello",
+    "ClassName": "Model",
+    "Children": [
+        {
+            "Name": "Some Part",
+            "ClassName": "Part"
+        },
+        {
+            "Name": "Some StringValue",
+            "ClassName": "StringValue",
+            "Properties": {
+                "Value": {
+                    "Type": "String",
+                    "Value": "Hello, world!"
+                }
+            }
+        }
+    ]
+}

+# Why Rojo?
+There are a number of existing plugins for Roblox that move code from the filesystem into Roblox.
+
+Besides Rojo, there is:
+
+* [Studio Bridge](https://github.com/vocksel/studio-bridge) by [Vocksel](https://github.com/vocksel)
+* [RbxRefresh](https://github.com/osyrisrblx/RbxRefresh) by [Osyris](https://github.com/osyrisrblx)
+* [RbxSync](https://github.com/evaera/RbxSync) by [evaera](https://github.com/evaera)
+* [CodeSync](https://github.com/MemoryPenguin/CodeSync) and [rbx-exteditor](https://github.com/MemoryPenguin/rbx-exteditor) by [MemoryPenguin](https://github.com/MemoryPenguin)
+* [rbxmk](https://github.com/anaminus/rbxmk) by [Anaminus](https://github.com/anaminus)
+
+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 the 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.
