+- Make sure you install the pre-commit hooks by running `pre-commit install` in the root of the project. If you don't have pre-commit in your computer, you can follow the installation instructions in the [pre-commit website](https://pre-commit.com/). When you commit locally, if pre-commit finds any errors it will abort the commit and make corrections. You will then need to commit again, adding the corrected files. Pre-commit will also run automatically as part of the PR checks and changes won't be merged unless the PR passes all checks.
