 To install the current development version you just need to run this in your terminal:
 
-	haxelib git openfl-tiled-flixel git@github.com:kasoki/openfl-tiled-flixel.git dev
+	haxelib git openfl-tiled-flixel https://github.com/kasoki/openfl-tiled-flixel dev
 
 ### Usage
 
 You just need to use FlxTiledMap instead of TiledMap:
 
-	var map = FlxTiledMap.fromAssets("assets/map.tmx");
-	
-	this.add(map); // FlxTiledMap is a FlxGroup
+```haxe
+var map = FlxTiledMap.fromAssets("assets/map.tmx");
+
+this.add(map); // FlxTiledMap is a FlxGroup
+```
 
 Each layer is a FlxGroup of FlxSprites (each tile is a FlxSprite) which are not active (which means that the update method is not called). If you want to make a layer active to use it e.g. for collision detection read the snippet below:
 
-	// TODO: add flixel import statements here
-	import openfl.tiled.FlxTiledMap;
-	import openfl.tiled.FlxLayer;
+```haxe
+// TODO: add flixel import statements here
+import openfl.tiled.FlxTiledMap;
+import openfl.tiled.FlxLayer;
 
-	class TiledTestState extends FlxState {
+class TiledTestState extends FlxState {
+	
+	private var map:FlxTiledMap;
+	private var sprite:FlxSprite;
+	
+	// FlxLayer is a FlxGroup of tiles
+	private var colliderLayer:FlxLayer;
+	
+	public override function create():Void {
+		super.create();
+		
+		map = FlxTiledMap.fromAssets("assets/map/test.tmx");
 		
-		private var map:FlxTiledMap;
-		private var sprite:FlxSprite;
+		sprite = new FlxSprite(30, 30);
+		sprite.makeGraphic(32, 32, FlxColor.RED);
 		
-		// FlxLayer is a FlxGroup of tiles
-		private var colliderLayer:FlxLayer;
+		sprite.acceleration.y = 200;
 		
-		public override function create():Void {
-			super.create();
-			
-			map = FlxTiledMap.fromAssets("assets/map/test.tmx");
-			
-			sprite = new FlxSprite(30, 30);
-			sprite.makeGraphic(32, 32, FlxColor.RED);
-			
-			sprite.acceleration.y = 200;
-			
-			// get the layer named "collider"
-			colliderLayer = map.getLayerByName("collider");
-			
-			// set the layer to active (update method will be called -> collision detection will be enabled)
-			colliderLayer.setActive(true);
-			
-			this.add(map);
-			this.add(sprite);
-		}
+		// get the layer named "collider"
+		colliderLayer = map.getLayerByName("collider");
 		
-		public override function destroy():Void {
-			super.destroy();
-		}
+		// set the layer to active (update method will be called -> collision detection will be enabled)
+		colliderLayer.setActive(true);
+		
+		this.add(map);
+		this.add(sprite);
+	}
+	
+	public override function destroy():Void {
+		super.destroy();
+	}
+	
+	public override function update():Void {
+		super.update();
 		
-		public override function update():Void {
-			super.update();
-			
-			FlxG.collide(sprite, colliderLayer);
-		}
+		FlxG.collide(sprite, colliderLayer);
 	}
+}
+```
