-This is optional and not required to contribute to this repository.

-### Installation

-Follow the [instructions](https://pre-commit.com/#install) provided with pre-commit and run `pre-commit install` under the repository base. If for any reason you would like to disable the pre-commit hooks run `pre-commit uninstall`.

-This is optional to run it locally.
-
-You can trigger it locally with `pre-commit run --all-files` or even to run only for a given file `pre-commit run --files YOUR_FILE`.
