+How to contribute
+=================
+
+.. note::
+
+   See `CONTRIBUTING.md <https://github.com/canonical/github-runner-operators/blob/main/CONTRIBUTING.md>`_
+   for information on contributing to the source code. 
+
+Our documentation is hosted on `Read the Docs <https://documentation.ubuntu.com/github-runner-operators>`_ to enable collaboration.
+Please use the links on each documentation page to either
+directly change something you see that's wrong, ask a question, or make a suggestion
+about a potential change.
+
+Our documentation is also available alongside the
+`source code on GitHub <https://github.com/canonical/github-runner-operators>`_.
+You may open a pull request with your documentation changes, or you can
+`file a bug <https://github.com/canonical/github-runner-operators/issues>`_
+to provide constructive feedback or suggestions.
+
+AI usage
+--------
+
+You are free to use any tools you want while preparing your contribution, including
+AI, provided that you do so lawfully and ethically. 
+
+Avoid using AI to complete
+`Canonical Open Documentation Academy issues <https://github.com/canonical/open-documentation-academy/issues>`_.
+The purpose of these issues is to provide newcomers with opportunities to
+contribute to our projects and gain documentation skills. Using AI to
+complete these tasks undermines their purpose.
+
+If you use AI to help with your PRs, be mindful. Avoid submitting contributions
+with entirely AI-generated documentation. The human aspect of documentation is
+important to us, and that includes tone, syntax, perspectives, and the
+occasional typo. 
+
+Some examples of valid AI assistance includes:
+
+* Checking for spelling or grammar errors
+* Drafting plans or outlines
+* Checking that your contribution aligns with the Canonical style guide
+
+We have created instructions and tools that you can provide AI while preparing
+your contribution in `copilot-collections <https://github.com/canonical/copilot-collections>`_.
+While it isn't necessary to use ``copilot-collections`` while preparing your
+contribution, these files contain details about our documentation standards and
+practices that will help the AI avoid common pitfalls when interacting with our
+projects. By using these tools, you can avoid longer review times and nitpicks.
