+## Release
+
+This project follows [Conventional Commits](https://www.conventionalcommits.org/) and uses a manual release workflow.
+
+1. Ensure `dist/` is up-to-date by running `npm run bundle`
+2. Trigger the **Release** workflow via `workflow_dispatch` with the desired [semver](https://semver.org/) version
+    - The workflow bumps `package.json`, creates a signed commit, and tags `v{version}`
+3. The **Changelog** workflow automatically regenerates `CHANGELOG.md` from conventional commits using [git-cliff](https://git-cliff.org/)
