 ## Create a Kubernetes cluster
 
-Use the `az aksarc create` command to create a Kubernetes cluster in AKS Arc. Make sure you sign in to Azure before running this command. If you have multiple Azure subscriptions, select the appropriate subscription ID using the [az account set](/cli/azure/account#az-account-set) command.
+Use the `[az aksarc create](/cli/azure/aksarc?view=azure-cli-latest#az-aksarc-create)` command to create a Kubernetes cluster in AKS Arc. Make sure you sign in to Azure before running this command. If you have multiple Azure subscriptions, select the appropriate subscription ID using the [az account set](/cli/azure/account#az-account-set) command. With the  `az aksarc create` command, we recommend you use the `--validate` flag, that validates the input parameters that you intend to use. Once the input parameters are validated, you can run the  `az aksarc create` command without the `--validate` flag to create the Kubernetes cluster. 
 
 ```azurecli
 az aksarc create -n $aksclustername -g $resource_group --custom-location $customlocationID --vnet-ids $logicnetId --aad-admin-group-object-ids $aadgroupID --generate-ssh-keys
