 ## Using a built in renderer

 Following this calling `Engine.run(engine)` will spawn the built in game loop routine, which will automatically manage updating the engine and calling the renderer at the appropriate times.
 
+#### Matter.RenderPixi
+
+An alternate renderer [Matter.RenderPixi](http://brm.io/matter-js-docs/classes/RenderPixi.html) is provided as an example of using [Pixi.js](http://www.pixijs.com/) to render a world using WebGL and a scene graph. The features available should match those of `Matter.Render` although sometimes there may be implementation differences.

 ## Using a custom renderer
 
 While the built in renderers are useful for early development, if you need to do any kind of complex rendering effects you will need a custom renderer.
