+		Helper tool to access and edit [Mesh] data.
 	</brief_description>
 	<description>
+		The MeshDataTool provides access to individual vertices in a [Mesh]. It allows users to read and edit vertex data of meshes. It also creates an array of faces and edges.
+		To use the MeshDataTool, load a mesh with [method create_from_surface]. When you are finished editing the data commit the data to a mesh with [method commit_to_surface].
+		Below is an example of how the MeshDataTool may be used.
+		[codeblock]
+		var mdt = MeshDataTool.new()
+		mdt.create_from_surface(mesh, 0)
+		for i in range(mdt.get_vertex_count()):
+			var vertex = mdt.get_vertex(i)
+			...
+			mdt.set_vertex(i, vertex)
+		mesh.surface_remove(0)
+		mdt.commit_to_surface(mesh)
+		[/codeblock]
