+Thank you for submitting a Pull Request (PR) to the LLVM Project!

+You can add reviewers by using the "Reviewers" section on this page.
+
+If this is not working for you, it's probably because you don't have write
+permissions for the repository. In which case you can instead tag reviewers by
+name in a comment by using `@` followed by their GitHub username.
+
+If you have received no comments on your PR for a week, you can request a review
+by "ping"ing the PR by adding a comment “Ping”. The common courtesy "ping" rate
+is once a week. Please remember that you are asking for valuable time from other developers.
+
+If you have further questions, they may be answered by the [LLVM GitHub User Guide](https://llvm.org/docs/GitHub.html).
