+## Extending Plugins
+
+### NuGet Package
+The NuGet package for **IW4MAdmin's** "Shared Library" can be obtained from the [NuGet Gallery](https://www.nuget.org/packages/RaidMax.IW4MAdmin.SharedLibraryCore)
+Referencing this package will give you the ability to write plugins against **IW4MAdmin's** core library.
+### Code
+**IW4MAdmin's** functionality can be extended by writing additional plugins in C#.  
+Each class library must implement the `IPlugin` interface.   
+See the existing [plugins](https://github.com/RaidMax/IW4M-Admin/tree/master/Plugins) for examples.
+### JavaScript
+**IW4MAdmin** functionality can also be extended using JavaScript.
+The JavaScript parser supports [ECMA 5.1](https://ecma-international.org/ecma-262/5.1/) standards.
+### Plugin Object Template
+In order to be properly parsed by the JavaScript engine, every plugin must conform to the following template.
+```js
+var plugin = {
+    author: 'YourHandle',
+    version: 1.0,
+    name: 'Sample JavaScript Plugin',
+
+    onEventAsync: function (gameEvent, server) {
+    },
+
+    onLoadAsync: function (manager) {
+    },
+
+    onUnloadAsync: function () {
+    },
+
+    onTickAsync: function (server) {
+    }
+};
+```
+### Required Properties
+- `author` — [string] Author of the plugin (usually your name or online name/alias)
+- `version` — [float] Version number of your plugin (useful if you release several different versions)
+- `name` — [string] Name of your plugin (be descriptive!)
+- `onEventAsync` — [function] Handler executed when an event occurs
+    - `gameEvent` — [parameter object] Object containing event type, origin, target, and other info (see the GameEvent class declaration)
+    - `server` — [parameter object] Object containing information and methods about the server the event occured on (see the Server class declaration)  
+- `onLoadAsync` — [function] Handler executed when the plugin is loaded by code
+    - `manager` — [parameter object] Object reference to the application manager (see the IManager interface definition) 
+- `onUnloadAsync` — [function] Handler executed when the plugin is unloaded by code (see live reloading)
+- `onTickAsync` — [function] Handler executed approximately once per second by code *(unimplemented as of version 2.\*)*
+    - `server` — [parameter object] Object containing information and methods about the server the event occured on (see the Server class declaration) 
+### Live Reloading
+Thanks to JavaScript's flexibility and parsability, the plugin importer scans the plugins folder and reloads the JavaScript plugins on demand as they're modified. This allows faster development/testing/debugging.
