-## Deployment on Unraid
+## Deployment with Portainer
 
-1. Copy the project directory to your Unraid server or build it via git.
-2. Create `/mnt/user/appdata/theme-song-booth/data` and `/mnt/user/appdata/theme-song-booth/uploads`.
-3. Copy `.env.example` to `.env`, fill in real values, and place it next to `docker-compose.yml`.
-4. Run `docker compose up -d --build`.
-5. Initialize the database once: `docker compose exec booth python init_db.py`.
-6. Point your chosen domain at the Unraid server's public IP and route it through your reverse proxy to `http://127.0.0.1:8000`.
-7. Print the booth QR code pointing to `https://your-domain.example.com/request`.
+The repo includes a `docker-compose.yml` that builds directly from GitLab, so Portainer can pull and deploy it as a stack.
+
+1. Log in to your Portainer instance.
+2. Go to **Stacks** → **Add stack**.
+3. Choose **Repository** and paste:
+   - URL: `https://gitlab.hallsworth.ca/yrtria/theme-song-booth.git`
+   - Branch: `main`
+   - Compose path: `docker-compose.yml`
+4. Add environment variables in Portainer (or upload a `.env` file):
+   - `APP_SECRET_KEY`
+   - `ADMIN_PASSWORD_HASH`
+   - `SMTP_PASS`
+   - `PUBLIC_BASE_URL` (your HTTPS domain)
+   - `ADMIN_ALERT_EMAIL`
+5. Deploy the stack.
+6. Open a console into the `booth` container and run once:
+   ```bash
+   python init_db.py
+   ```
+7. Point your reverse proxy (Nginx Proxy Manager, Traefik, Caddy, etc.) at `http://host-ip:8000` on the chosen domain.
+8. Print the booth QR code pointing to `https://your-domain/request`.
+
+### Portainer Notes
+
+- The `docker-compose.yml` uses named volumes (`booth-data`, `booth-uploads`) so Portainer handles persistence automatically.
+- For a pre-built image instead of repo build, replace the `build:` block with an `image:` line pointing to your registry.
+- Update the stack after each push to redeploy the latest code.
