 `SkipUnsupportedTest` simply skips any tests that you define there.
 
-Depending on your plugin's specs, you would implement other driver interaces defined [here](https://github.com/kubernetes/kubernetes/blob/master/test/e2e/storage/testsuites/testdriver.go#L61). For example the [NFS testdriver](https://github.com/mathu97/csi-driver-nfs/blob/master/test/nfs_driver.go) also implements PreprovisionedVolumeTestDriver, and PreprovisionedPVTestDriver, to enable pre-provisoned tests.

For example the [NFS testdriver](https://github.com/mathu97/csi-driver-nfs/blob/master/test/nfs_driver.go) also implements PreprovisionedVolumeTestDriver, and PreprovisionedPVTestDriver interfaces, to enable pre-provisoned tests. 
 
+After implementing the tesdriver for your CSI plugin, you would create a `csi-volumes.go` file, where the implemented testdriver is used to run in-tree storage test suites [similar to how the NFS testdriver does](https://github.com/mathu97/csi-driver-nfs/blob/master/test/csi-volumes.go#L38). 
 
+Finally, importing the test package from your [main test file](https://github.com/mathu97/csi-driver-nfs/blob/master/cmd/nfsplugin/nfsplugin_test.go#L5) will allow all the in-tree storage tests to run.
+
+A command similar to this would be used to run the end-to-end tests:
+
+```
+go test -v <main test file> -ginkgo.v -ginkgo.progress --kubeconfig=<kubeconfig file> -timeout=0
