 When you install Kubernetes, choose an installation type based on: ease of maintenance, security,
 control, available resources, and expertise required to operate and manage a cluster.
 
-You can deploy a Kubernetes cluster on a local machine, cloud, on-prem datacenter, or choose a managed Kubernetes cluster. There are also custom solutions across a wide range of cloud providers, or bare metal environments.
+You can [download Kubernetes](/releases/download/) to deploy a Kubernetes cluster
+on a local machine, into the cloud, or for your own datacenter.
+
+If you don't want to manage a Kubernetes cluster yourself, you could pick a managed service, including
+[certified platforms](/docs/setup/production-environment/turnkey-solutions/).
+There are also other standardized and custom solutions across a wide range of cloud and
