@jmagak I’ve added some suggestions for the title, subtitle, and abstract. Please take a look when you get a chance and let me know if they look good to you.

I’ve also drafted a disclaimer and shared it with Emily for review. Once it’s approved, I’ll pass it along so we can incorporate it as well.

Thank you so much, Heena for these great suggestions and generally for the huge work with this.

Regarding the feedback from test day, to provide additional clarification:
Parts 1.1–1.4 are performed inside the RHDH application (source repo / image build), so changes to the RHDH instance itself.
Parts 2–3 (ArgoCD configuration and Application annotations) are cluster-level steps executed via oc and apply directly to the OpenShift environment hosting ArgoCD.

Possibly we could add a short section to the beginning about what will need to be updated and where - maybe a short list of the steps needed to be done and where they will be executed? However, this documentation is very much aimed at platform engineers (who will probably understand this even from the diagram), not just regular developers, as changes in the cluster need to be done to make this feature work. It would maybe be worth pointing this out in the beginning of the tutorial as well, just so that readers understand that this is quite a technical topic and not something that can be configured by anyone.
