Contributing is always welcome!
I am no professional flask developer, if you know a better way that something can be done, please let me know!
Otherwise, it's always best to PR into the dev branch.
Please be sure that all new functionality has a matching test!
Use pytest to validate/test, you can run the existing tests as pytest tests/test_notifications.py for example
pip3 install -r requirements-dev
