+### Disabling Local Saving
+
+You can disable local saving of audio files and hide the file view in the UI by setting the `DISABLE_LOCAL_SAVING` environment variable to `true`. This is useful when running the service on a server where you don't want to store generated audio files locally.
+
+When using Docker Compose:
+```yaml
+environment:
+  - DISABLE_LOCAL_SAVING=true
+```
+
+When running the Docker image directly:
+```bash
+docker run -p 7860:7860 -e DISABLE_LOCAL_SAVING=true ghcr.io/remsky/kokoro-fastapi-ui:latest
+```
