+<!--
+- Please ensure code changes are split into a series of logically independent commits.
+- Every commit should have a subject/title (What) and a description/body (Why).
+- Every PR must have a description.
+- As an example you can use git commit -m"What" -m"Why" to achieve the requirements above.
+  GitHub automatically recognizes the commit description (-m"Why") in single commit PRs and
+  adds it as the PR description.
+- Use the [imperative mood](https://en.wikipedia.org/wiki/Imperative_mood) in the subject line
+  for every commit. E.g `Mark infraID as required` instead of `This patch marks infraID as required`
+  (This follows Git’s own built-in conventions). See https://github.com/openshift/hypershift/pull/485
+  as an example.
+- See https://github.com/redhat-openshift-ecosystem/opct/blob/main/CONTRIBUTING.md for more details.
+
+Delete this text before submitting the PR.
