+# How To Use Persistent Volumes
+
+This guide assumes knowledge of Kubernetes fundamentals and that a user has a cluster up and running.
+
+## Create volumes
+
+Persistent Volumes are intended for "network volumes", such as GCE Persistent Disks, NFS shares, and AWS EBS volumes.
+
+The `HostPath` VolumeSource was included in the Persistent Volumes implementation for ease of testing.
+ 
+Create persistent volumes by posting them to the API server:
+
+```
+
+cluster/kubectl.sh create -f examples/persistent-volumes/volumes/local-01.yaml
+cluster/kubectl.sh create -f examples/persistent-volumes/volumes/local-02.yaml
+
