 	<brief_description>
+		A collection of [code]NavigationMesh[/code] resources and methods used for pathfinding.
 	</brief_description>
 	<description>
+		The Navigation node is used for basic or advanced navigation. By default it will automatically collect all child [code]NavigationMesh[/code] resources, but they can also be added on the fly through scripting. It can be used for generating a simple path between two points or it can be used to ensure that a navigation agent is angled perfectly to the terrain it is navigating.
