GraphGist / adoc capabilities?

I am just getting started with neo4j. I was hoping to start by documenting and providing examples of how I intend to organize the project nodes and relationships at a general level. I saw the GraphGist (https://portal.graphgist.org/submit_graphgist). Questions:

  1. I was not able to get the web page https://portal.graphgist.org/submit_graphgist to generate a preview -- is it broken?
  2. It looks like graghgist is basically an extension of .adoc so that neo4j/cypher can be embedded in a doc -- can I use this locally with neo4j desktop and create local .adoc's?

Thanks for the help,
Bob.
