How to troubleshoot default community health files

Hello, community. I have been trying to use a default README.md for my organization, but it does not show up. Here’s the timeline of events:

  1. Created organization
  2. Created repo (not a .github repo) with a README.md
  3. Created .github repo with a README.md
  4. Deleted the 1st repo’s README.md
    Both repos are public. The .github README is in the root. Shouldn’t the default file work now that there is no matching file in the 1st repo? I have browsed the docs.github.com tutorial and the discussions here, but I see nothing related to this problem.
    Are there any common errors I should look into?

README.md doesn’t seem to be one of the Supported File Types.

Thank you for pointing that out; I really should have noticed that. Sorry for the foolish question.

No worries, everyone has those days.
