Your terminal program must respond to these commands:
In general, homebrew with rbenv and heroku packages are your friend here.
Whether from government representatives or from interested citizens, inbound interest in coming online with Citygram is relatively healthy. Sometimes there will be a pull request, sometimes there won't be. Sometimes they will have read the documentation, sometimes they won't have read it.

This is basically "acquire their code to run it locally"
