Before continuing, make sure that the virtual environment is set up and activated.
To run the admin application with Flask’s (insecure!) development server for development purposes:
(venv)$ BYCEPS_CONFIG=../config/development.py APP_MODE=admin FLASK_ENV=development flask run --debugger --reload
The admin application should now be reachable at http://127.0.0.1:5000 (on Flask’s standard port).
