@@ -12,6 +12,7 @@ Create a nodal Lobatto-Legendre basis for polynomials of degree `polydeg`.
 
 For the special case `polydeg=0` the DG method reduces to a finite volume method.
 Therefore, this function sets the center point of the cell as single node.
+This exceptional case is currently only supported for TreeMesh!
