 ## Getting Started
 
-GraphScope can run on clusters managed by [Kubernetes](https://kubernetes.io/) within containers. For quickly getting started, we can leverage [minikube](https://minikube.sigs.k8s.io/) (on Linux) to set up a *local* Kubernetes cluster and take advantage of pre-built Docker images as follows.
