-# Kubernetes Template Project
-
-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:
-
-- 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.
+# CSI ISCSI driver
+
+## Usage:
+
+### Start ISCSI driver
+```
+$ sudo ./_output/iscsidriver --endpoint tcp://127.0.0.1:10000 --nodeid CSINode
+```
+
+### Test using csc
+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
+"ISCSI"	"0.1.0"
+```
+
+#### NodePublish a volume
+```
+$ export ISCSI_TARGET="iSCSI Target Server IP (Ex: 10.10.10.10)"
+$ export IQN="Target IQN"
+$ csc node publish --endpoint tcp://127.0.0.1:10000 --target-path /mnt/iscsi --attrib targetPortal=$ISCSI_TARGET --attrib iqn=$IQN --attrib lun=<lun-id> iscsitestvol
+iscsitestvol
+```
+
+#### NodeUnpublish a volume
+```
+$ csc node unpublish --endpoint tcp://127.0.0.1:10000 --target-path /mnt/iscsi iscsitestvol
+iscsitestvol
+```
+
+#### Get NodeID
+```
+$ csc node get-id --endpoint tcp://127.0.0.1:10000
+CSINode
+```
