 The highlighted portion is the scale set resource definition. To create a scale with a template, you define the appropriate resources. The core parts of the virtual machine scale set resource type are:

+#### Add a sample application
 
 To test your scale set, install a basic web application. When you deploy a scale set, VM extensions can provide post-deployment configuration and automation tasks, such as installing an app. Scripts can be downloaded from Azure storage or GitHub, or provided to the Azure portal at extension run-time. To apply an extension to your scale set, you add the *extensionProfile* section to the preceding resource example. The extension profile typically defines the following properties:

 ## Clean up resources
+
 When no longer needed, you can use [az group delete](/cli/azure/group) to remove the resource group, scale set, and all related resources as follows. The `--no-wait` parameter returns control to the prompt without waiting for the operation to complete. The `--yes` parameter confirms that you wish to delete the resources without an additional prompt to do so.
 
 ```azurecli-interactive
 az group delete --name myResourceGroup --yes --no-wait

 In this quickstart, you created a Linux scale set with an Azure template and used the Custom Script Extension to install a basic Python web server on the VM instances. To learn more, continue to the tutorial for how to create and manage Azure virtual machine scale sets.
