+## Running pre-commit
+
+We use [pre-commit](https://pre-commit.com/) to lint and validate submissions.
+
+Setting up `pre-commit` is straightforward; see the [Installation](https://pre-commit.com/#installation) documentation on the `pre-commit` site for details.
+
+We highly suggest you install the local `git` hook scripts as well; run `pre-commit install` within the root of the project.
+
+Lastly, you can run the hooks prior to committing changes (and PR submission) by executing `pre-commit run -a`.
