 ## cuGraph Notice
 
-Vertex IDs are expected to be contiguous integers starting from 0.  If your data doesn't match that restriction, we have a solution.  cuGraph provides the renumber function, which is by default automatically called when data is addted to a graph.  Input vertex IDs for the renumber function can be any type, can be non-contiguous, can be multiple columns, and can start from an arbitrary number. The renumber function maps the provided input vertex IDs to either 32- or 64-bit contiguous integers starting from 0.

 Additionally, when using the auto-renumbering feature, vertices are automatically un-renumbered in results.
