Updates NFS-setup README
# Setting up an NFS Server on AML Arc
-More detailed documentation can be found here https://github.com/Azure/AML-Kubernetes/blob/master/docs/setup-ephemeral-nfs-volume.md
+Before you can run any of the examples in this section you will need to setup an NFS mount on your
+Arc-enabled Kubernetes cluster.
+
+The included mount-config.yaml file can be used as a template to do this. You will need to replace `<nfs-server-ip>` with the
+actual address of your server. Then run the following:
+
+```
+kubectl apply -f mount-config.yaml
+```
+
+More detailed documentation on ephemeral NFS volume usage in Arc-enabled Machine Learning
+can be found [here](../../../docs/setup-ephemeral-nfs-volume.md)
