And you can also declare body parameters as optional, by setting the default to `None`:

{* ../../docs_src/body_multiple_params/tutorial001_an_py310.py hl[18:20] *}

/// note

Notice that, in this case, the `item` that would be taken from the body is optional. As it has a `None` default value.

Install this chart using:

```bash
helm install --namespace minio --set rootUser=rootuser,rootPassword=rootpass123 --generate-name minio/minio
```

The command deploys MinIO on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.

### Installing the Chart (toy-setup)
