-## Overview
-
-You can execute your distributed Ray programs on a Kubernetes cluster.
-
-The [KubeRay Operator](https://ray-project.github.io/kuberay/components/operator/) provides a Kubernetes-native
-interface for managing Ray clusters. Each Ray cluster consist of a head pod and collection of worker pods.
-Optional autoscaling support allows the KubeRay Operator to size your Ray clusters according to the requirements
-of your Ray workload, adding and removing Ray pods as needed.
-
-## Learn More
-
-The Ray docs present all the information you need to start running Ray workloads on Kubernetes.
