+For Two-Node with Fencing (TNF), only the following platforms are supported:
+- baremetal
+- external
+- none

 For platform `none`:
 
 * The `none` option requires the provision of DNS name resolution and load balancing infrastructure in your cluster. See _Requirements for a cluster using the platform "none" option_ in the "Additional resources" section for more information.
 
 * Review the information in the link:https://access.redhat.com/articles/4207611[guidelines for deploying {product-title} on non-tested platforms] before you attempt to install an {product-title} cluster in virtualized or cloud environments.
