How do I clone a GitHub wiki?

Any GitHub wiki can be cloned by appending wiki.git to the repo url, so the clone url for the repo https://myorg/myrepo/ is: git@github.com:myorg/myrepo.wiki.git (for ssh) or https://github.com/my/myrepo.wiki.git (for https).

You make edits, and commit and push your changes, like any normal repo. This wiki repo is distinct from any clone of the project repo (the repo without wiki.get appended).

# More of a reference of using jinaj2 without actual template files.
# This is great for a simple output transformation to standard out.

# Of course you will need to "sudo pip install jinja2" first!
