+## RFCs
+
+The Lit project handles "significant" changes and feature requests via our [RFC (Request for Comment) Process](https://github.com/lit/rfcs).
+
+Medium-to-large feature requests should be done via RFC, and feature request issues may be closed after asking that they be submitted as an RFC. If you're wondering whether there's interest in an idea before creating an RFC, file an [RRFC issue](https://github.com/lit/rfcs#before-opening-an-rfc) in https://github.com/lit/rfcs to discuss it.

 ## Pull Requests
 
 Pull requests are greatly appreciated! To ensure a smooth review process, please follow these steps:
 
-1.  Make sure there's an open issue that the PR addresses. Add "Fixes #(issue number)" to the PR description.
+1.  Make sure there's an open issue or RFC that the PR addresses. If there's an issue, add "Fixes #(issue number)" to the PR description.
 2.  Please discuss the general shape of the change ahead of time. This can save much time for reviewers and submitters alike. Many times there may be existing ideas on how to handle an issue that are not fully written out, and asking about it will bring out more details.
 3.  All PRs that change behavior or fix bugs should have new or updated tests.
 4.  Try to create a set of descriptive commits that each do one focused change. Avoid commits like "oops", and prefer commits like "Added method foo to Bar".
