+#### github_alpine-specific notes
+
+`artifactapi_remote_github_alpine` is the Alpine/apk analog of `github_rpm`: it
+exposes a GitHub repo's release `.apk` assets as an `apk` repository, synthesizing
+the apk index (`APKINDEX.tar.gz`) from release metadata 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 `.apk` bytes; `.apk` downloads
+302-redirect there. `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_alpine/main.tf`.
