 	<description>
-		Base node for 2D system. Node2D contains a position, rotation and scale, which is used to position and animate. It can alternatively be used with a custom 2D transform ([Transform2D]). A tree of Node2Ds allows complex hierarchies for animation and positioning.
+		A 2D game object, with a position, rotation and scale. All 2D physics nodes and sprites inherit from Node2D. Use Node2D as a parent node to move, scale and rotate children in a 2D project. Also gives control on the node's render order.
