+## Running pre-commit
+
+[pre-commit](https://github.com/pre-commit/pre-commit) is a framework for managing pre-commit git hooks. The pre-commit git hooks are ways to identify issues in your code before pushing your changes to the repository, for instance missing semicolons, trailing whitespace, unused dependancies.

+To run pre-commit on your code, run:

+```
+uv run pre-commit run --all
+```
