How to use git pre-commit hooks

Make sure you have black, flake8, and pre-commit installed into your environment.

pip install black
pip install flake8
pip install pre-commit

Then create .pre-commit-config.yaml in the root directory of your repository and run:

pre-commit install

This will put all your pre-commit hooks into .git/hooks/ and make sure they are enforced before every commit.
