+## 🚀 Launch the Conversational UI (Optional)
+
+To access the Conversational UI (react based) frontend, modify the UI service in the `compose.yaml` file. Replace `chaqna-xeon-ui-server` service with the `chatqna-xeon-conversation-ui-server` service as per the config below:
+
+```yaml
+chaqna-xeon-conversation-ui-server:
+  image: opea/chatqna-conversation-ui:latest
+  container_name: chatqna-xeon-conversation-ui-server
+  environment:
+    - APP_BACKEND_SERVICE_ENDPOINT=${BACKEND_SERVICE_ENDPOINT}
+    - APP_DATA_PREP_SERVICE_URL=${DATAPREP_SERVICE_ENDPOINT}
+  ports:
+    - "5174:80"
+  depends_on:
+    - chaqna-xeon-backend-server
+  ipc: host
+  restart: always
+```
+
+Once the services are up, open the following URL in your browser: http://{host_ip}:5174. By default, the UI runs on port 80 internally. If you prefer to use a different host port to access the frontend, you can modify the port mapping in the `compose.yaml` file as shown below:
+
+```yaml
+  chaqna-xeon-conversation-ui-server:
+    image: opea/chatqna-conversation-ui:latest
+    ...
+    ports:
+      - "80:80"
+```
