LIBRARY

To run this app in development setting, first create a virtual environment for
installing Flask. Install the requirements. Then, initialise the database and
run the application.

You can do that using the following commands:

    python3 -m venv venv
    pip3 install -r requirements.txt
    flask --app library init-db
    flask --app library run --debug

If wanted you can also generate some mock data using:

    flask --app library mock-data

but make sure your database is empty beforehand!
