# Deploy AzureML extension to your Kubernetes cluster
+AzureML extension can be easily installed with a single ```az k8s-extension create``` command. But according to your needs and deployment scenarios, different parameters and pre-checkings should be paid attention to, like K8s distro, cluster resources, networking, security, storage and AML features.
+
+For a quick test scenario, please try the following two happy paths with [Minikube](#install-with-minikube) and [AKS](#install-with-aks) clusters respectively. For special production needs, please refer to the corresponding sections below. For any errors or failures, please refer to [Trouble Shooting](./troubleshooting.md).
