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
```
