Release 7.0.0-alpha.3

* web/mod.rs - change server bind address

127.0.0.1 is a loopback interface, and only works on the same host
0.0.0.0 will allow connections from other hosts

ideally, this should be a console arg - but it's a quick fix

* implement --address option, revert default bind address to 127.0.0.1

* revert silly autoformatting

* ok, actually using rustfmt now

* More precise --address flag description

* Use SocketAddr where available, take advantage of const-ness

* Display 'localhost' if address is loopback

* Update Changelog

 ## Unreleased Changes
 
+## [7.0.0-alpha.3][7.0.0-alpha.3] (February 19, 2021)
+* Updated dependencies, fixing `OptionalCoordinateFrame`-related issues.
+* Added `--address` flag to `rojo serve` to allow for external connections. ([#403][pr-403])
+
+[pr-403]: https://github.com/rojo-rbx/rojo/pull/403
+[7.0.0-alpha.3]: https://github.com/rojo-rbx/rojo/releases/tag/v7.0.0-alpha.3
+
+## [7.0.0-alpha.2][7.0.0-alpha.2] (February 19, 2021)
+* Fixed incorrect protocol version between the client and server.
+
+[7.0.0-alpha.2]: https://github.com/rojo-rbx/rojo/releases/tag/v7.0.0-alpha.2
+
+## [7.0.0-alpha.1][7.0.0-alpha.1] (February 18, 2021)
+This release includes a brand new implementation of the Roblox DOM. It brings performance improvements, much better support for `rbxl` and `rbxm` files, and a better internal API.
+
+* Added support for all remaining property types.
+* Added support for the entire Roblox binary model format.
+* Changed `rojo upload` to upload binary places and models instead of XML.
+    * This should make using `rojo upload` much more feasible for large places.
+* **Breaking**: Changed format of some types of values in `project.json`, `model.json`, and `meta.json` files.
+    * This should impact few projects. See [this file][allValues.json] for new examples of each property type.
+
+Formatting of types will change more before the stable release of Rojo 7. We're hoping to use this opportunity to normalize some of the case inconsistency introduced in Rojo 0.5.

+

+* Fixed `rojo upload` to handle CSRF challenges.
+
+## [6.0.1](https://github.com/rojo-rbx/rojo/releases/tag/v6.0.1) (January 22, 2021)

+
+## [6.0.0](https://github.com/rojo-rbx/rojo/releases/tag/v6.0.0) (January 16, 2021)
+* Improved server error messages
+    * The server will now keep running in more error cases
+* Fixed Rojo being unable to diff ClassName changes
+
+## [6.0.0 Release Candidate 4](https://github.com/rojo-rbx/rojo/releases/tag/v6.0.0-rc.4) (December 14, 2020)
+* Added brand new Rojo UI ([#367](https://github.com/rojo-rbx/rojo/pull/367))
+* Added `projectName` to `/api/rojo` output.
+
+## [6.0.0 Release Candidate 3](https://github.com/rojo-rbx/rojo/releases/tag/v6.0.0-rc.3) (November 19, 2020)
+* Fixed the Rojo plugin attempting to write the non-scriptable properties `Instance.SourceAssetId` and `HttpServer.HttpEnabled`.
+* Fixed the Rojo plugin's handling of null referents.
+
+## [6.0.0 Release Candidate 2](https://github.com/rojo-rbx/rojo/releases/tag/v6.0.0-rc.2) (November 19, 2020)
+* Fixed crash when malformed CSV files are put into a project. ([#310](https://github.com/rojo-rbx/rojo/issues/310))
+* Fixed incorrect string escaping when producing Lua code from JSON files. ([#314](https://github.com/rojo-rbx/rojo/issues/314))
+* Fixed performance issues introduced in Rojo 6.0.0-rc.1. ([#317](https://github.com/rojo-rbx/rojo/issues/317))
+* Fixed `rojo plugin install` subcommand failing for everyone except Rojo developers. ([#320](https://github.com/rojo-rbx/rojo/issues/320))
+* Updated default place template to take advantage of [#210](https://github.com/rojo-rbx/rojo/pull/210).
+* Enabled glob ignore patterns by default and removed the `unstable_glob_ignore` feature.
+    * `globIgnorePaths` can be set on a project to a list of globs to ignore.
+* The Rojo plugin now completes as much as it can from a patch without disconnecting. Warnings are shown in the console.
+* Fixed 6.0.0-rc.1 regression causing instances that changed ClassName to instead... not change ClassName.
+
+## [6.0.0 Release Candidate 1](https://github.com/rojo-rbx/rojo/releases/tag/v6.0.0-rc.1) (March 29, 2020)
+This release jumped from 0.6.0 to 6.0.0. Rojo has been in use in production for many users for quite a long times, and so 6.0 is a more accurate reflection of Rojo's version than a pre-1.0 version.
+
+* 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.
+* Added support for turning `.json` files into `ModuleScript` instances ([#308](https://github.com/rojo-rbx/rojo/pull/308))
+* Added `rojo plugin install` and `rojo plugin uninstall` to allow Rojo to manage its Roblox Studio plugin. ([#304](https://github.com/rojo-rbx/rojo/pull/304))
+* Class names no longer need to be specified for Roblox services in Rojo projects. ([#210](https://github.com/rojo-rbx/rojo/pull/210))
+* The server half of **experimental** two-way sync is now enabled by default.
+* Increased default logging verbosity in commands like `rojo build`.
+* Rojo now requires a project file again, just like 0.5.4.
+
+## [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.

-# 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
-```

-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.

-
-## 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))

-
-## 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
-            },
-
-            "Terrain": {
-                "$path": "Terrain.rbxm"
-            }
-        }
-    }

-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!

+
+Implementation of a virtual filesystem with a configurable backend and file
+watching.
+
+memofs is currently an unstable minimum viable library. Its primary consumer is
+[Rojo](https://github.com/rojo-rbx/rojo), a build system for Roblox.
+
+### Current Features
+* API similar to `std::fs`
+* Configurable backends
+    * `StdBackend`, which uses `std::fs` and the `notify` crate
+    * `NoopBackend`, which always throws errors
+    * `InMemoryFs`, a simple in-memory filesystem useful for testing
+
+### Future Features
+* Hash-based hierarchical memoization keys (hence the name)
+* Configurable caching (write-through, write-around, write-back)

+Implementation of a virtual filesystem with a configurable backend and file
+watching.
+
+memofs is currently an unstable minimum viable library. Its primary consumer is
+[Rojo](https://github.com/rojo-rbx/rojo), a build system for Roblox.
+
+## Current Features
+* API similar to `std::fs`
+* Configurable backends
+    * `StdBackend`, which uses `std::fs` and the `notify` crate
+    * `NoopBackend`, which always throws errors
+    * `InMemoryFs`, a simple in-memory filesystem useful for testing
+
+## Future Features
+* Hash-based hierarchical memoization keys (hence the name)
+* Configurable caching (write-through, write-around, write-back)
