+Run Pre-Commit Tests Locally
+----------------------------
+
+When proposing code changes to Warpx, we perform a couple of automated stylistic and correctness checks on the code change.
+You can run those locally before you push to save some time, install them once like this:
+
+.. code-block:: sh
+
+   python -m pip install -U pre-commit
+   pre-commit install
+
+See `pre-commit.com <https://pre-commit.com>`__ and our ``.pre-commit-config.yaml`` file in the repository for more details.
