Thanks for taking this on! Overall feedback on this page:

Naming consistency

There’s heavy use of “Web Modeler on Self-Managed”, which reads awkwardly and isn’t aligned with how we refer to components elsewhere in the docs. It also starts to feel like a product rename.

Suggested approach:

• Use Web Modeler (Self-Managed) in the title or when distinction is needed.
• Use Web Modeler throughout the body text unless the SM distinction affects meaning.
• Avoid repeating “on Self-Managed” in every paragraph.

Sidebar behavior

The sidebar currently shows “Overview” as a separate item.
For consistency with other components, clicking Web Modeler should take the reader directly to this overview page. No separate “Overview” entry should be needed.

Redundant heading

The page starts with:

Web-Modeler on Self-Managed

…and then immediately has another heading:

About Web Modeler on Self-Managed

Maybe we could remove the second header or just leave it as "About"? Feels redundant.

Improve clarity and tone

Some phrases are vague:

“Run Camunda's modeling experience in your own infrastructure.”

Consider being more concrete:

“Web Modeler lets teams design, review, and version BPMN and DMN diagrams directly in your Self-Managed environment.”

@christinaausley I addressed your reviews. I decided to remove the About section - I agree it feels a bit redundant after seeing it again today. Ready for another pass, thanks!

Looks awesome, great work 💪 Happy to re-approve once backported.
