This is a less optimal solution because you have to re-copy the entire folder of documentation each time a change is made. I'm still working on a smoother fix.
It's fine to just accept all the default, but make sure you enable autodoc when you are asked about it.
Put this file in the root of the documentation, docs/. You may also get an ImportError with autodoc that requires you to put a copy of the repository's setup.py in docs/. Why this is necessary is a profound and uninteresting mystery.
