+# Set up a NFS Server on a Kubernetes cluster
+
+To create a NFS provisioner on your Kubernetes cluster, run the following command
+
+```bash
+kubectl create -f https://raw.githubusercontent.com/kubernetes-csi/nfs-driver-smb/master/examples/kubernetes/nfs-provisioner/nfs-server.yaml
+```
+
+After deploying, a new service `nfs-server` is created. The file share path is accessible at `nfs-server.default.svc.cluster.local/nfsshare`.
+
+To obtain a public IP for the service, run the following command instead
+
+```bash
+kubectl create -f https://raw.githubusercontent.com/kubernetes-csi/nfs-driver-smb/master/examples/kubernetes/nfs-provisioner/nfs-server-lb.yaml
+```
