In the August 30 Community & Governance Board meeting, we agreed to update our roadmap process by structuring our roadmaps into GitHub projects.

TODO:

• [x] Update Community documentation to explain the process
  • https://github.com/tektoncd/community/pull/813
• [ ] Make a Roadmap project for automated tracking of Roadmap items
• [ ] Update per-repo roadmaps to point at the project:
  • [ ] community
  • [ ] resolution
  • [ ] chains
  • [ ] pipeline
  • [ ] website
  • [ ] cli
  • [ ] catalog
  • [ ] hub
  • [ ] results
  • [ ] triggers
• [ ] 🎉
