 The HTTP application routing add-on can be enabled with the Azure CLI when deploying an AKS cluster. To do so, use the [az aks create][az-aks-create] command with the `--enable-addons` argument.
 
 ```azurecli
-az aks create --resource-group myAKSCluster --name myAKSCluster --enable-addons http_application_routing
+az aks create --resource-group myResourceGroup --name myAKSCluster --enable-addons http_application_routing
 ```
 
-After the cluster is deployed, use the [az aks show][az-aks-show] command to retrieve the DNS zone name. This name is needed to deploy applications to the AKS cluster.
+You can also enable HTTP routing on an existing AKS cluster using the [az aks enable-addons][az-aks-enable-addons] command. To enable HTTP routing on an existing cluster, add the `--addons` parameter and specify *http_application_routing* as shown in the following example:
 
 ```azurecli
-$ az aks show --resource-group myAKSCluster --name myAKSCluster --query addonProfiles.httpApplicationRouting.config.HTTPApplicationRoutingZoneName -o table
+az aks enable-addons --resource-group myResourceGroup --name myAKSCluster --addons http_application_routing
+```

+After the cluster is deployed or updated, use the [az aks show][az-aks-show] command to retrieve the DNS zone name. This name is needed to deploy applications to the AKS cluster.

+```azurecli
+$ az aks show --resource-group myResourceGroup --name myAKSCluster --query addonProfiles.httpApplicationRouting.config.HTTPApplicationRoutingZoneName -o table

 The HTTP routing solution can be removed using the Azure CLI. To do so run the following command, substituting your AKS cluster and resource group name.
 
 ```azurecli
