 # Navigation Polygon 2D
 
-Example of using 2D navigation using a
-[`NavigationPolygon`](https://docs.godotengine.org/en/latest/classes/class_navigationpolygon.html)
-in a [`NavigationPolygonInstance`](https://docs.godotengine.org/en/latest/classes/class_navigationpolygoninstance.html) node.
-It uses the 2D navigation API to request a path between two points,
-and then traverses the resulting path.
+Example of using 2D navigation using:
