+
+## Docker
+
+За пълно ръководство за Docker deployment вижте [Docker Guide](docker.md).
+
+### Бърз старт
+
+```bash
+docker build -t baradb:latest .
+docker compose up -d
+```
+
+### Docker Compose файлове
+
+| Файл | Назначение |
+|------|-----------|
+| `docker-compose.yml` | Development |
+| `docker-compose.prod.yml` | Production |
+| `docker-compose.override.yml` | Dev override (автоматично) |
+| `docker-compose.test.yml` | Тестова среда |
+
+### Production
+
+```bash
+docker compose -f docker-compose.prod.yml up -d
+```
+
+### Docker Swarm
+
+```bash
+docker stack deploy -c docker-compose.prod.yml baradb
+```
+
+## systemd Услуга
+
+Създайте `/etc/systemd/system/baradb.service`:
