+CSI node plugins need to perform various privileged
+operations like scanning of disk devices and mounting of file systems. These operations
+differ for each host operating system. For Linux worker nodes, containerized CSI node
+node plugins are typically deployed as privileged containers. For Windows worker nodes,
+privileged operations for containerized CSI node plugins is supported using
+[csi-proxy](https://github.com/kubernetes-csi/csi-proxy), a community-managed,
+stand-alone binary that needs to be pre-installed on each Windows node.

+For more details, refer to the deployment guide of the CSI plugin you wish to deploy.

 FlexVolume is deprecated. Using an out-of-tree CSI driver is the recommended way to integrate external storage with Kubernetes.
