+## GitHub Release
+
+GitHub Releases are generated automatically when a version tag is pushed.
+
+```bash
+git tag v2.1.1
+git push origin v2.1.1
+```
+
+The release workflow strips the optional `v` prefix and builds the library with that version. It uploads:
+
+- `counttimeprogressview-<version>.aar`
+- `counttimeprogressview-<version>-sources.jar`
+- `counttimeprogressview-<version>.pom`
+- `counttimeprogressview-<version>.module`
+- `counttimeprogressview-<version>.zip`
