 ## Testing
 
-`tox` will run [pytest](http://pytest.org/) under every supported version of Python thanks to [tox](https://bitbucket.org/hpk42/tox).
-
-To restrict the versions of Python tested by `tox`, you can use `tox -e py312,pypy` for example.
+Run `python -m pytest` and see [.github/workflows/zeyple.yml](./.github/workflows/zeyple.yml) for the full testing workflow.
