+#### github_rpm-specific notes
+
+`artifactapi_remote_github_rpm` exposes a GitHub repo's releases as a `dnf`/`yum`
+repository without precaching packages. Set `base_url` to the releases API root
+(`https://api.github.com/repos/{owner}/{repo}`) and `releases_remote` to a
+generic `github.com` remote that streams the `.rpm` bytes. `patterns` filters
+which release assets become packages (regex on asset filename). `password` may
+hold a token for private repos or higher API rate limits. See
+`examples/resources/artifactapi_remote_github_rpm/main.tf`.
