+.NAME
+	attach-SharedDisks.ps1
+
+.DESCRIPTION
+The script will scan a resource group for machines. It will then show a list of VMs available.
+Once a VM (or more) is selected, the data disks will be offered. From the selected disks, shared disks will be attached to all the VMs.
+
+.PERMISSIONS REQUIRED
+    Contributor
+.USE CASES
+
+.Parameters
+$ResourceGroupName - resource group containing VMs with cluster disks
+$startingLunNumber - number to use as a starting LUN to attach disks. Default is 0 (assuming VM has no data disks).
+$DisksResourceGroup - Resource group containing the disks to be attached
+$linux - uses a linux compatible out-consolegridview to show the options.
