 Here are the instructions to create custom Avere Roles:
-  1. "avere-cluster" - use instructions from [the Avere documention for runtime role creation](https://docs.microsoft.com/en-us/azure/avere-vfxt/avere-vfxt-pre-role).  Microsoft employees use role "Avere Cluster Runtime Operator".
-  1. "Avere Contributor" - apply the ["Avere Contributor" role file](src/roles/AvereContributor.txt), using instructions from [the Avere documention for runtime role creation](https://docs.microsoft.com/en-us/azure/avere-vfxt/avere-vfxt-pre-role).  Microsoft employees specify role "Avere Cluster Create".
+  1. "avere-cluster" - use instructions from [the Avere documention for runtime role creation](https://docs.microsoft.com/en-us/azure/avere-vfxt/avere-vfxt-pre-role).  Microsoft employees should specify already defined role "Avere Cluster Runtime Operator".

Microsoft employees should specify already defined role "Avere Cluster Create".
    
 There are two deployment modes of the Avere vFXT: standalone and "bring your own VNET".  In the standalone case, the deployment deploys the controller and vFXT cluster into a brand new VNET.  In the "bring your own VNET" deployment, the controller and vFXT cluster uses ip addresses from an existing vnet subnet.  Both of these cases require different role configurations.  The following two sections highlight show the strictest scoping to a service principal, but these can be generalized to any user principal.
