+# Getting Started #
+
+System Requirements:
+* [Node.js](https://nodejs.org/en/) v7.9.0+
+
+This repository is dedicated to the development of the new custom launcher for the [WesterosCraft](http://www.westeroscraft.com/) server. This project is developed primarily with [Node.js](https://nodejs.org/en/) and the [Electron](https://electron.atom.io/) framework. For further reference you may view [the repository of the new launcher written in JavaFX/Java](https://gitlab.com/westeroscraft/WesteroscraftNewLauncher) which was discontinued. You may also view the repository of the [current launcher](https://gitlab.com/westeroscraft/westeroscraftlaunchercore), a modified fork of MCUpdater.
+
+For authentication with Mojang, we are currently planning on using [node-mojang](https://github.com/jamen/node-mojang). This will automatically be downloaded if you follow the simple installation instructions below.
+
+### Recommended IDE ###
+
+The recommended IDE for this project is [VS Code](https://code.visualstudio.com/), an open source code editor by Microsoft. This editor is available on nearly every major platform (Windows, macOS, Linux). If you choose to use another editor, such as [Atom](https://atom.io/), please gitignore the IDE specific settings directory, if it hasn't been already.
+
+### Installation ###
+
+To begin working on this project clone the repository and open run the following command on the command line. This will download all of the required dependencies.
+
+```shell
+npm install
+```
+
+# Launching #
+
+### Command Line ###
+
+There are several different ways to launch this project. One way is simply to run the following command on the command line.
+
+```shell
+npm start
+```
+
+### Visual Studio Code ###
+
+If you use VS Code, you can run this directly from the IDE. Copy the following code into your launch.json file. This will require you to also install [Debugger for Chrome](https://marketplace.visualstudio.com/items?itemName=msjsdiag.debugger-for-chrome).
+
+```json
+{
+  "version": "0.2.0",
+  "configurations": [
+    {
+      "name": "Debug Main Process",
+      "type": "node",
+      "request": "launch",
+      "cwd": "${workspaceRoot}",
+      "runtimeExecutable": "${workspaceRoot}\\node_modules\\.bin\\electron",
+      "windows": {
+        "runtimeExecutable": "${workspaceRoot}\\node_modules\\.bin\\electron.cmd"
+      },
+      "program": "${workspaceRoot}\\index.js",
+      "console": "integratedTerminal",
+      "protocol": "legacy"
+    },
+    {
+      "name": "Debug Renderer Process",
+      "type": "chrome",
+      "request": "launch",
+      "runtimeExecutable": "${workspaceRoot}\\node_modules\\.bin\\electron",
+      "windows": {
+        "runtimeExecutable": "${workspaceRoot}\\node_modules\\.bin\\electron.cmd"
+      },
+      "runtimeArgs": [
+        "${workspaceRoot}\\index.js",
+        "--remote-debugging-port=9222"
+      ],
+      "webRoot": "${workspaceRoot}"
+    }
+  ]
+}
+```
+
+This will create two launch configurations from which you can debug the launcher. The first configuration, **Debug Main Process**, will allow you to debug the main Electron process. The second configuration, **Debug Renderer Process**, will allow you to debug the rendering of web pages (ie the UI).
+
+You can find more information [here](http://code.matsu.io/1).
+
+### Notes on DevTools Window ###
+
+Once you run the program, you can open the DevTools window by typing the following keys in sequence on the main window.
+
+```shell
+wcdev
+```
+
+Please note that if you are debugging the application with VS Code and have launched the program using the **Debug Renderer Process** configuration you cannot open the DevTools window. If you attempt to do so, the program will crash. Remote debugging cannot be  done with multiple DevTools clients.
+

+/**
+ * AssetGuard
+ * 
+ * This module aims to provide a comprehensive and stable method for processing
+ * and downloading game assets for the WesterosCraft server. A central object
+ * stores download meta for several identifiers (categories). This meta data
+ * is initially empty until one of the module's processing functions are called.
+ * That function will process the corresponding asset index and validate any exisitng
+ * local files. If a file is missing or fails validation, it will be placed into an
+ * array which acts as a queue. This queue is wrapped in a download tracker object
+ * so that essential information can be cached. The download tracker object is then
+ * assigned as the value of the identifier in the central object. These download
+ * trackers will remain idle until an async process is started to process them.
+ * 
+ * Once the async process is started, any enqueued assets will be downloaded. The central
+ * object will emit events throughout the download whose name correspond to the identifier
+ * being processed. For example, if the 'assets' identifier was being processed, whenever
+ * the download stream recieves data, the event 'assetsdlprogress' will be emitted off of
+ * the central object instance. This can be listened to by external modules allowing for
+ * categorical tracking of the downloading process.
