In Chapter 5. Schema and Data Modeling first there is paragraph:

The default cardinality setting is SINGLE. Note, that property keys used on edges and properties have cardinality SINGLE. Attaching multiple values for a single key on an edge or property is not supported.

and then example:

mgmt = graph.openManagement()
follow = mgmt.makeEdgeLabel('follow').multiplicity(MULTI).make()

I feel that README.md is currently a little too complex for someone who is using gremgo for the first time, particularly the structure and the code examples. If anybody feels like it, I think the project would benefit greatly from a rewrite of the documentation.

When your looking at a graph, it would be nice to hover a node to see more of it's information.
