# Values in this file are loaded into the flask app instance, `demo.APP` in this
# demo. This file sources values from the environment if they exist, otherwise a
# set of defaults are used. This is useful for keeping secrets secret, as well
# as facilitating configuration in a container. Defaults may be overriden either
# by defining the environment variables, or by creating a `config.py` file that
# contains locally set secrets or config values.
