+# Create a two node SQL Server Always On Cluster with SQL 2016 on Windows Server 2016
+
+This template deploys two SQL Server Enterprise, Standard or Developer instances in an Always On Availability Group. It creates the following resources:
+
+* A network security group
+* A virtual network
+* Four storage accounts (One for AD, One for SQL, One for File Share witness and One for VM diagnostic)
+* Four public IP address (One for AD, Two for each SQL VM and One for Public LB bound to SQL Always On Listener)
+* One external load balancer for SQL VMs with Public IP bound to the SQL Always On listener
+* One VM (WS2016) configured as Domain Controller for a new forest with a single domain
+* Two VM (WS2016) configured as SQL Server 2016 SP1 or SP2 Enterprise/Standard/Developer and clustered (must use the marketplace images)
+* One VM (WS2016) configured as File Share Witness for the cluster
+* One Availability Set containing the SQL and FSW 2016 VMs
+
+## Notes
+
+This template uses Azure Stack Marketplace images. These need to be available on your Azure Stack instance:
+
+* Windows Server 2016 Datacenter Image (for AD and FSW VMs)
+* Choice of SQL Server 2016 SP1 or SP2 on Windows Server 2016 (Enterprise, Standard or Developer)
+* Latest SQL IaaS Extension 1.2.x (currently 1.2.30)
+* Latest DSC Extension (2.76.0, or higher)
+* Latest Custom Script Extension for Windows (1.9.1, or higher)
+
+## Configuration
+
+* Each SQL VMs will have the number and size of data disks specified, of up to 1TiB each. The SQL extension will configured these into a single volume using Storage Spaces.
+* The SQL VMs and the file share witness will be configured in an Availability Set
+  * Integrated Systems (fault domains:3, update domains:5)
+  * ASDK will automatically use fault domains:1, update domains:1)
+* The template configures the SQL instances with contained database authentication set to true.
+* The *external* DNS suffix for public IP addresses (ASDK default: azurestack.external)
