Summary

Add a new section to README.md that lists public open source GitHub repositories with 500+ stars that already use rumdl as part of their CI, with a link to each repository.

Motivation

Seeing real-world adoption makes it easier to evaluate rumdl, builds confidence, and provides examples of how to integrate rumdl into CI workflows.

Proposed README section

• Title suggestion: Used by / Who uses rumdl / Adopters
• For each entry, include:
  • Repository name (as a link)
  • Star count threshold note: "500+ stars at time of listing"
  • Optional: link directly to the workflow file or config snippet where rumdl is invoked

Maintenance approach (suggestion)

• Generate the list automatically (script + periodic update) to avoid it going stale.
• Document how a project can be added:
  • public repo
  • 500+ stars
  • uses rumdl in CI (GitHub Actions or similar)
  • include evidence (workflow link)

Acceptance criteria

• README.md includes a section with at least a few verified 500+ star repos using rumdl in CI.
• Each item links to the repository (and ideally the workflow/config where rumdl runs).
• Clear contribution instructions exist for adding/updating entries.
