+GitHub Releases attach only `main.js`, `manifest.json`, and `styles.css` as Obsidian install assets. `LICENSE` and `NOTICE` are kept in the repository and source archives for license distribution.
+
+Create a release by bumping `package.json`, `package-lock.json`, `manifest.json`, and `versions.json`, committing with `Bump version to X.Y.Z`, then pushing the matching tag:
+
+```sh
+git tag X.Y.Z
+git push origin main X.Y.Z
+```
+
+The release workflow runs `npm run check`, attaches the install assets, and generates GitHub artifact attestations for them. Review the generated GitHub release notes after the workflow finishes and edit them when a release needs hand-written notes.
