 # Quickstart: Create and modify an ExpressRoute circuit using Azure PowerShell
 
-This quickstart shows you how to create an ExpressRoute circuit using PowerShell cmdlets and the Azure Resource Manager deployment model. You can also check the status, update, delete, or deprovision a circuit.
+This quickstart shows you how to create an ExpressRoute circuit in three different resiliency types: **Maximum Resiliency**, **High Resiliency**, and **Standard Resiliency** using Azure PowerShell. You'll learn how to check the status, update, delete, or deprovision a circuit using PowerShell cmdlets.

+### Get the list of resilient locations
+
+If you're creating an ExpressRoute circuit with a resiliency type of  **Maximum Resiliency**, you need to know the list of resilient locations. Here are the steps to retrieve this information:
+
+#### Clone the script
+
+1. Clone the setup script from GitHub. 
+
+   ```azurepowershell-interactive
+   git clone https://github.com/Azure-Samples/azure-docs-powershell-samples/ 
+   ```
+
+1. Change to the directory where the script is located.
+
+   ```azurepowershell-interactive
+   CD azure-docs-powershell-samples/expressroute/
+   ```
+
+#### Run the script
+
+Run the **Get-AzExpressRouteResilientLocations.ps1** script to get the list of resilient locations. The following example shows how to get the resilient locations for a specific subscription sorted by distance from Silicon Valley:
+
+```azurepowershell-interactive
+$SubscriptionId = Get-AzureSubscription -SubscriptionName "<SubscriptionName>"
+highAvailabilitySetup/Get-AzExpressRouteResilientLocations.ps1 -SubscriptionId $SubscriptionId -RelativeLocation "silicon valley"
+```
+If you don't specify the location, you get a list of all resilient locations.
