+The project adopted the ``autopep8`` tool to assist with
+automatic code formatting. It is chosen over ``black``
+because it is less intrusive which is important to the
+maintainer as it promotes inclusivity.
+``autopep8`` is integrated into the ``pre-commit`` check
+runner and is configured to only correct :pep:`8`
+violations, avoiding changes to compliant snippets.
