Things will work most smoothly if your admin repository is reachable at
../admin
relative to this repository. If it's not, you should set
your SWCARPENTRY_ADMIN_PATH
environment variable to the location of
the admin repository on your machine.
Then, from the root directory of this repository, run:
virtualenv venv
source venv/bin/activate
pip install -r requirements.txt
python app.py
At this point you can visit http://127.0.0.1:5000/ to use the web interface.
