Replace the values in .env.example with your values and rename this file to .env:

FLASK_APP: Entry point of your application (should be wsgi.py).
FLASK_ENV: The environment to run your app in (either development or production).
SECRET_KEY: Randomly generated string of characters used to encrypt your app's data.

Remember never to commit secrets saved in .env files to Github.
