 1. Verify that the subnet is correctly delegated:
 
+   ```
    az network vnet subnet show \\  \--resource-group \$RESOURCE_GROUP \--vnet-name \$VNET_NAME  \--name \$SUBNET_NAME  \--query delegations
+   ```
 
 1. Make sure that the output shows **Microsoft.ContainerService/managedClusters** as the delegated service or no delegated service. If the output shows any Azure service delegation, you have to remove it by running the following command:
 
+   ```
    az network vnet subnet update  \--resource-group \$RESOURCE_GROUP
    \--vnet-name \$VNET_NAME  \--name \$SUBNET_NAME \--remove delegations 0
-
+   ```
+   
 1. Run the following command to add Managed Cluster delegation:
 
+   ```
    az network vnet subnet update  \--resource-group \$RESOURCE_GROUP
    \--vnet-name \$VNET_NAME  \--name \$SUBNET_NAME \--delegations
    Microsoft.ContainerService/managedClusters
+   ```
 
 1. After the subnet delegation is removed, try again to create the node pool by using the `az aks nodepool add` command.
