+Adhere to code style
+--------------------
+
+Ansys Sphinx theme follows the PEP8 standard as outlined in
+`PEP 8 <https://dev.docs.pyansys.com/coding-style/pep8.html>`_ in
+the *PyAnsys Developer's Guide* and implements style checking using
+`pre-commit <https://pre-commit.com/>`_.
+
+To ensure your code meets minimum code styling standards, run these commands::
+
+  pip install pre-commit
+  pre-commit run --all-files
+
+or use tox as above::
+
+    tox -e code-style
+
+You can also install this as a pre-commit hook by running this command::
+
+  pre-commit install
+
+This way, it's not possible for you to push code that fails the style checks::
+
+  $ pre-commit install
+  $ git commit -am "added my cool feature"
