 ## Quick Start
 
 ```bash
 cp .env.example .env
 # Edit TELEGRAM_BOT_TOKEN and POSTGRES_PASSWORD in .env
-docker compose up -d
+docker compose up -d --build
+```
+
+On first boot, Postgres init scripts run automatically in order:
+
+1. `00-run-init.sh` — creates roles (authenticator, dashboard_user)
+2. `01-init.sql` — creates tables and indexes
+3. `post-boot.sql` — applies grants on created tables
+
+## Deployment
+
+### Unraid + Portainer
+
+1. Set the Docker Compose project path to `/mnt/user/appdata/willhaben-tracker`
+2. Ensure `.env` is present with valid credentials
+3. Deploy via Portainer: **Stacks → Add stack**, paste `docker-compose.yml` contents and attach `.env`
+4. Postgres data persists at `/mnt/user/appdata/willhaben-tracker/data/db`
+
+### Manual (Linux)
+
+```bash
+cd /path/to/willhaben-tracker
+cp .env.example .env
+# Edit .env with your credentials
+docker compose up -d --build
 ```
