 ## Requirements
 
-* Kubernetes v1.17 or above. 
+* Kubernetes v1.20 or above (Oracle Linux Cloud Native Environment 1.3)
-* A Container runtime implementing the Kubernetes Container Runtime Interface. This plugin was tested with CRI-O v1.17.
+* A Container runtime implementing the Kubernetes Container Runtime Interface (ex. CRI-O)
 * An Oracle ZFS Storage Appliance running Appliance Kit Version 8.8 or above. This plugin may work with previous 
   versions but it is not tested with them. It is possible to use this 
   driver with the [Oracle ZFS Storage Simulator](https://www.oracle.com/downloads/server-storage/sun-unified-storage-sun-simulator-downloads.html)
 * Access to both a management path and a data path for the target Oracle 
   ZFS Storage Appiance (or simulator). The management and data path 
-can be the same address.

 * A suitable container image build environment (podman or docker are accounted
   for in the makefile)
