 spine-haxe supports all Spine features except premultiplied alpha atlases and two color tinting.
 
 ## Setup
+The core module of spine-haxe has zero dependencies. The rendering implementation through Starling has two dependencies: openfl and starling.
+To use spine-haxe you have first to install all the necessary dependencies:
+
+```
+haxelib install openfl
+haxelib install starling
+```
+
+Once you have installed the dependencies, you can [download the latest version of spine-haxe](https://esotericsoftware.com/files/spine-haxe/4.2/spine-haxe-latest.zip) and install it:
 
-TBD
+```
+haxelib install spine-haxe-x.y.z.zip
+```
+
+Notice that the spine-haxe library is not available on [lib.haxe.org](https://lib.haxe.org/). This is why you need to download the library and install it through the zip archive.
 
 ## Example
 
-TBD
+The `example/` folder contains the spine-haxe examples. They demonstrates the usage of the API. Enter the the `spine-haxe` folder and run the following command:
+
+```
+lime test html5
+```
+
+This will compile the modules and start a server that serves the example pages at http://127.0.0.1:3000.
