    source venv/bin/activate
    pip install -r requirements.txt

    ./manage.py migrate
    ./manage.py createsuperuser
 Fill the user info, launch django with ``./manage.py runserver`` and head over
 to `http://127.0.0.1:8000/ <http://127.0.0.1:8000/>`_, you can also
 `login to the admin <http://127.0.0.1:8000/admin>`_ with the credentials your
 provided.
