+## Libraria PixiJS
+
+# Introdução
+
+O PixiJS é uma libraria em Javascript que permite efetuar a manipulação dos objectos 2D utilizando o WebGL através do uso do Canvas.
+
+# Exemplo de código
+
+Coelho rotativo
+```
+var app = new PIXI.Application(800, 600, {backgroundColor : 0x1099bb});
+document.body.appendChild(app.view);
+
+// create a new Sprite from an image path
+var bunny = PIXI.Sprite.fromImage('required/assets/basics/bunny.png')
+
+// center the sprite's anchor point
+bunny.anchor.set(0.5);
+
+// move the sprite to the center of the screen
+bunny.x = app.screen.width / 2;
+bunny.y = app.screen.height / 2;
+
+app.stage.addChild(bunny);
+
+// Listen for animate update
+app.ticker.add(function(delta) {
+    // just for fun, let's rotate mr rabbit a little
+    // delta is 1 if running at 100% performance
+    // creates frame-independent transformation
+    bunny.rotation += 0.1 * delta;
+});
+
+```
