CSI allows vendors to create custom storage plugins for Kubernetes without adding them to the Kubernetes repository (out-of-tree plugins). To use a CSI driver from a storage provider, you must first [deploy it to your cluster](https://kubernetes-csi.github.io/docs/Setup.html). You will then be able to create a {{<glossary_tooltiptext="Storage Class"term_id="storage-class">}} that uses that CSI driver.
