-# Kubernetes Template Project
+# CSI NFS driver
 
-The Kubernetes Template Project is a template for starting new projects in the GitHub organizations owned by Kubernetes. All Kubernetes projects, at minimum, must have the following files:
+## Kubernetes
+### Requirements
 
-- a `README.md` outlining the project goals, sponsoring sig, and community contact information
-- an `OWNERS` with the project leads listed as approvers ([docs on `OWNERS` files][owners])
-- a `CONTRIBUTING.md` outlining how to contribute to the project
-- an unmodified copy of `code-of-conduct.md` from this repo, which outlines community behavior and the consequences of breaking the code
-- a `LICENSE` which must be Apache 2.0 for code projects, or [Creative Commons 4.0] for documentation repositories, without any custom content
-- a `SECURITY_CONTACTS` with the contact points for the Product Security Team 
-  to reach out to for triaging and handling of incoming issues. They must agree to abide by the
-  [Embargo Policy](https://github.com/kubernetes/sig-release/blob/master/security-release-process-documentation/security-release-process.md#embargo-policy) 
-  and will be removed and replaced if they violate that agreement.
+The folllowing feature gates and runtime config have to be enabled to deploy the driver
+
+```
+FEATURE_GATES=CSIPersistentVolume=true,MountPropagation=true
+RUNTIME_CONFIG="storage.k8s.io/v1alpha1=true"
+```
+
+Mountprogpation requries support for privileged containers. So, make sure privileged containers are enabled in the cluster.
+
+### Example local-up-cluster.sh
+
+```ALLOW_PRIVILEGED=true FEATURE_GATES=CSIPersistentVolume=true,MountPropagation=true RUNTIME_CONFIG="storage.k8s.io/v1alpha1=true" LOG_LEVEL=5 hack/local-up-cluster.sh```
+
+### Deploy
+
+```kubectl -f deploy/kubernetes create```
+
+### Example Nginx application
+Please update the NFS Server & share information in nginx.yaml file.
+
+```kubectl -f examples/kubernetes/nginx.yaml create```
+
+## Using CSC tool
+
+### Build nfsplugin
+```
+$ make nfs
+```
+
+### Start NFS driver
+```
+$ sudo ./_output/nfsplugin --endpoint tcp://127.0.0.1:10000 --nodeid CSINode -v=5
+```
+
+## Test
+Get ```csc``` tool from https://github.com/rexray/gocsi/tree/master/csc
+
+#### Get plugin info
+```
+$ csc identity plugin-info --endpoint tcp://127.0.0.1:10000
+"NFS"	"0.1.0"
+```
+
+#### NodePublish a volume
+```
+$ export NFS_SERVER="Your Server IP (Ex: 10.10.10.10)"
+$ export NFS_SHARE="Your NFS share"
+$ csc node publish --endpoint tcp://127.0.0.1:10000 --target-path /mnt/nfs --attrib server=$NFS_SERVER --attrib share=$NFS_SHARE nfstestvol
+nfstestvol
+```
+
+#### NodeUnpublish a volume
+```
+$ csc node unpublish --endpoint tcp://127.0.0.1:10000 --target-path /mnt/nfs nfstestvol
+nfstestvol
+```
+
+#### Get NodeID
+```
+$ csc node get-id --endpoint tcp://127.0.0.1:10000
+CSINode
+```
