 ### Submitting PRs for Protobuf Changes
 
-- Only submit PRs with changes to `.proto` files, CI will handle generating other files
-- Do not make breaking changes to APIs if it can be avoided
+- Only submit PRs with changes to `.proto` files, CI will handle generating other files.
+    - Upon (first) approval of the PR, file generation will happen.
+    - Wait for it to complete (it will add a `protos-compiled` label and new files to the PR) before merging.
+    - Do not make further changes after this point.
+    - If stuck waiting for merge checks _after_ `protos-compiled` is added, try adding an unrelated label (ex: `enhancement`) to trigger it again.
+- Do not make breaking changes to APIs if it can be avoided.
