.pre-commit-config.yaml

# pre-commit hooks require a user to have installed `pre-commit`:
#   $ brew install pre-commit
# Then install the hooks within the repo:
#   $ cd /PATH/TO/base-python3 (or whatever your package is located)
#   $ pre-commit install
# You only need to run the `install` once per repo

# note that you can update the `sha` versions in this file automatically with the command
# `pre-commit autoupdate`
