 Pre-commit is used for various style checking and code formatting.
 Before each commit, it will automatically run:
- - [black](https://black.readthedocs.io/en/stable/) a code formatter.
+ - [ruff](https://docs.astral.sh/ruff/) a code formatter and linter.
    This will automatically format your code.
    Make sure to take a second look after any formatting takes place,
    if the resulting code is very bloated, consider a (small) refactor.
