+## Description
+<!--- Describe your changes in detail -->

+## How Has This Been Tested?
+<!--- Please describe in detail how you tested your changes. -->
+<!--- Include details of your testing environment, and the tests you ran to -->
+<!--- see how your change affects other areas of the code, etc. -->
+
+Self checklist (all need to be checked):
+- [ ] Ensure that you have run `make test` (`gmake` on macOS) before asking for review
+- [ ] Changes to everything except `Dockerfile.konflux` files should be done in `odh/notebooks` and automatically synced to `rhds/notebooks`. For Konflux-specific changes, modify `Dockerfile.konflux` files directly in `rhds/notebooks` as these require special attention in the downstream repository and flow to the upcoming RHOAI release.

+<!--- Go over all the following points, and put an `x` in all the boxes that apply. -->

+- [ ] The commits are squashed in a cohesive manner and have meaningful messages.
+- [ ] Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
+- [ ] The developer has manually tested the changes and verified that the changes work
