+### GitHub Pages deployment
+
+The `Deploy GitHub Pages` workflow runs on every push to `main` (and can be run
+manually). It installs dependencies, runs tests and metadata validation, builds
+the Vite site, and publishes `dist` to GitHub Pages. In the repository's
+**Settings > Pages**, select **GitHub Actions** as the build and deployment
+source. This replaces the previous `gh-pages` branch publishing setup; keep
+that branch until the first workflow deployment succeeds.
+
 ## GitHub Import Workflow
 
 1. Paste a GitHub repository URL into the import field.
