-For maintainers troubleshooting deployment issues, see [docs/DEPLOYMENT_SETUP.md](docs/DEPLOYMENT_SETUP.md) for:
-- Verifying trusted publishing configuration on npmjs.com
-- Required workflow and job name settings
-- Troubleshooting authentication errors
-- Testing deployment with pre-release versions
+Releases are published by the `deploy` job of `.github/workflows/test-and-release.yml` when a version tag is pushed. The npm package must list this repository and that workflow as a trusted publisher on npmjs.com, no `NPM_TOKEN` secret is needed. See the [npm trusted publishing documentation](https://docs.npmjs.com/trusted-publishers) for setup and troubleshooting.
