+We format our code using [Black](https://github.com/python/black) and verify the source code is black compliant
+in Appveyor during PRs. You can find installation instructions on [Black's docs](https://black.readthedocs.io/en/stable/installation_and_usage.html).

+After installing, you can run our formatting through our Makefile by `make black-format` or integrating Black directly in your favorite IDE (instructions
+can be found [here](https://black.readthedocs.io/en/stable/editor_integration.html))
+
+#### Pre-commit
+If you don't wish to manually run black on each pr or install black manually, we have integrated black into git hooks through [pre-commit](https://pre-commit.com/).
+After installing pre-commit, run `pre-commit install` in the root of the project. This will install black for you and run the black formatting on
