 ### Adding support for a new storage platform in Kubernetes
-For folks looking to add support for a new storage platform in Kubernetes, you have several options:
-- Write an in-tree volume plugin or provisioner: You can contribute a new in-tree volume plugin or provisioner, that gets built and ships with Kubernetes, for use within the Persistent Volume Framework. 
-[See the Ceph RBD volume plugin example](https://git.k8s.io/kubernetes/pkg/volume/rbd) or [the AWS Provisioner example](https://github.com/kubernetes/kubernetes/pull/29006)
-- Write a FlexVolume plugin: This is an out-of-tree volume plugin which you develop and build separately outside of Kubernetes. 
-You then install the plugin on every Kubernetes host within your cluster and then [configure the plugin in Kubernetes as a FlexVolume](https://git.k8s.io/examples/staging/volumes/flexvolume)
-- Write a Provisioner Controller: You can write a separate controller that watches for pending claims with a specific selector label on them. 
-Once an appropriate claim is discovered, the controller then provisions the appropriate storage intended for the claim and creates a corresponding 
-persistent volume for the claim that includes the same label used in the original claim selector. This will ensure that the PV for the new 
-storage provisioned gets bound to the original claim.
+For folks looking to add support for a new storage platform in Kubernetes, take a look of the [CSI Drivers Doc](https://kubernetes-csi.github.io/docs/). The CSI Drivers Doc website documents how to develop, deploy, and test a [Container Storage Interface](https://github.com/container-storage-interface/spec/blob/master/spec.md) (CSI) driver on Kubernetes.
