+== Enabling pre-commit checks locally
+The repository has some basic commit checks set up with https://pre-commit.com/[pre-commit] that will be enforced by the GitHub CI.
+To ensure these checks are also run in the local repository while making changes the following command can be run:
+[source,shell]
+----
+pip3 install pre-commit && pre-commit install
+----
+
+When enabling additional checks https://pre-commit.com/#plugins[by editing .pre-commit-config.yaml], it is recommended to run to newly added check on all files in the repository. This can be done with the following command:
+[source,shell]
+----
+pre-commit run --all-files
+----
