It can be "Add your use case" link directing to the airflow-site/landing-pages/site/content/en/use-cases/ directory.

Hi maintainers 👋
I’d like to work on this issue. Please assign it to me.

Proposed change:
Add a clear Call-To-Action (CTA) on the Airflow Use cases page such as "Add your use case", linking to:
airflow-site/landing-pages/site/content/en/use-cases/_directory

Implementation plan:

• Find the Use cases page source in the repo and identify the best section for CTA placement (top banner / below title / end of page)

• Add a button-style CTA with consistent styling (same theme + typography as the site)

• Ensure it looks good on mobile + desktop and doesn’t break existing layout

• Test the link and verify it redirects correctly

• Open a PR with screenshots for review

I’ll start working on it once assigned. Thanks!
