+## Workshop deployment
 
-The workshop is powered by a [PocketBase](https://pocketbase.io) instance (GitHub OAuth, database,
-file uploads, and an admin moderation dashboard). The deployment lives in `apps/store/` with a
-`docker-compose.yml`, version-controlled collection migrations, and vote-counter hooks. See the
-app's `README.md` for GitHub OAuth setup and the `STORE_URL` / `NEXT_PUBLIC_WIDGET_STORE_URL`
-configuration.
+Workshop is powered by [PocketBase](https://pocketbase.io). The production image compiles the current Docusaurus site and serves it together with the API from one origin. The deployment lives in `apps/workshop/` with a Dockerfile, Compose configuration, version-controlled migrations, hooks, a smoke test, and ACT-local workflow instructions.
+
+Homarr instances use `NEXT_PUBLIC_WORKSHOP_API_URL` to reach the central API and `NEXT_PUBLIC_WORKSHOP_URL` for links to the public page. Docusaurus uses `WORKSHOP_URL` only when its development server runs separately; the combined production image always uses its own origin.
