 ## Red Hat OpenShift Container Platform version support policy
 
 Azure Red Hat OpenShift supports two generally available (GA) minor versions of Red Hat OpenShift Container Platform:
-* The latest GA minor version that is released in Azure Red Hat OpenShift (which we'll refer to as N)
+* The latest GA minor version that is released in Azure Red Hat OpenShift (referred to as N)
+
 * One previous minor version (N-1)
 
 If available in a stable upgrade channel, newer minor releases (N+1, N+2) available in upstream OCP are supported as well.
