To build the documentation, spin up a virtual environment using you favourite implementation, install the prereqs from requirements.txt and then run nox -s docs. For example on a mac using virtualenv:
> virtualenv .venv
> . .venv/bin/activate
> pip install -r requirements.txt
> nox -s docs
> open docs/_build/index.html
