# Pull Request Check List

This is just a friendly reminder about the most common mistakes.  Please make sure that you tick all boxes.  But please read our [contribution guide](https://www.attrs.org/en/latest/contributing.html) at least once, it will save you unnecessary review cycles!

If an item doesn't apply to your pull request, **check it anyway** to make it apparent that there's nothing left to do.  If your pull request is a documentation fix or a trivial typo, feel free to delete the whole thing.
