This is all relative to the dd-sso/admin directory.
With https://pipenv.pypa.io/en/latest/ it is simple to setup a
development environment (pipenv install --dev).
By running:
echo "PYTHONPATH=$(pwd)/src" > .env
The admin module will be loaded in the virtualenvironment and e.g.
running mypy src/admin will throw different errors in the existing code.
