+     This snippet deploys OpenWebUI version `0.5.10`. For the latest version replace `open-webui:0.5.10` by `open-webui:main`. Note that storage and memory requirements often increase with latest versions, as new features or built-in models may be included in the OpenWebUI container image. In this case, if the container is in `Error` state we recommend to increase `cpu-limit`, `memory-limit` or `local-storage-limit` values to recommended OpenWebUI values.
