 A great way to get involved is to pick an issue and help address it. We would love help here. Storage related issues are [listed here](https://github.com/kubernetes/kubernetes/issues?utf8=%E2%9C%93&q=is%3Aopen+is%3Aissue+label%3Asig%2Fstorage+).
 
 ### Adding support for a new storage platform in Kubernetes
-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.
