+### Docker Compose together with Open WebUI
+
+Using [Docker Compose](https://docs.docker.com/compose/) simplifies the management of multi-container Docker applications.
+
+Here is an example configuration file `docker-compose.yaml` for setting up Open WebUI together with Pipelines using Docker Compose:
+
+```yaml
+services:
+  openwebui:
+      image: ghcr.io/open-webui/open-webui:main
+      ports:
+        - "3000:8080"
+      volumes:
+        - open-webui:/app/backend/data
+
+  pipelines:
+      image: ghcr.io/open-webui/pipelines:main
+      volumes:
+        - pipelines:/app/pipelines
+      restart: always
+      environment:
+        - PIPELINES_API_KEY=0p3n-w3bu!
+
+volumes:
+  open-webui: {}
+  pipelines: {}
+```
+
+To start your services, run the following command:
+
+```
+docker compose up -d
+```
+
+You can then use `http://pipelines:9099` (the name is the same as the service's name defined in `docker-compose.yaml`) as an API URL to connect to Open WebUI.
+
+> [!NOTE]
+> The `pipelines` service is accessible only by `openwebui` Docker service and thus provide additional layer of security.
