-Currently this requires Python 3.6+ but the version requirements can drop a couple of minor versions easily if there is interest. Python 2.7 isn't planned to be supported as the Modello class relies on [PEP-3115](https://www.python.org/dev/peps/pep-3115/).

 ## Development
-Run the tests and linting with `python setup.py test`. Pushes have the test suite run against them, and will also publish a release if tagged thanks to GitHub Actions. You can reproduce the Actions locally using [act](https://github.com/nektos/act), e.g. `TWINE_USERNAME= TWINE_PASSWORD= act`.
