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 master branch.

Install the development and test dependencies with pip install -r requirements-dev.txt.

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_notification.py for example

New dependencies

Please check the licence before adding anything to requirements.txt. MIT, BSD, Apache-2.0, LGPL and MPL are fine; GPL and AGPL are not, since they would relicense the whole project. CI enforces this. There is usually a permissive equivalent - ask in the PR if you're not sure.
