+### Releasing a New Version
+
+When a new GitHub Release is created (e.g. `v0.2.0`), the package is **automatically published to npm** via GitHub Actions:
+
+```bash
+# Create a release — npm publish happens automatically
+gh release create v0.2.0 --title "v0.2.0" --generate-notes
+```
+
+The workflow syncs the version from the release tag, builds the standalone app, and publishes to npm.
