+To use this config after you install the Azureml extension with the configuration setting of `installVolcano=true`, you need to follow the steps below:  
+1. Create a configmap file with the above config in the azureml namespace. This namespace will generally be created when you install the AzureML extension.
+1. Set `volcanoSchedulerConfig=<configmap name>` in the extension config to apply this configmap. And you need to skip the resource validation when install the extension by configuring `amloperator.skipResourceValidation=true`. For example:
+    ```azurecli
+    az k8s-extension update --name <extension-name> --extension-type Microsoft.AzureML.Kubernetes --config volcanoSchedulerConfig=<configmap name> amloperator.skipResourceValidation=true --cluster-type managedClusters --cluster-name <your-AKS-cluster-name> --resource-group <your-RG-name> --scope cluster
