+short-description: |
+  A CLI tool that helps you create, destroy, upgrade and maintain production-grade, highly available, Kubernetes clusters. *NOTE: Officially supports AWS only, with GCE and VMware vSphere in alpha*.
+long-description: |
+  `kops` provisions your cluster with:
+
+    * Fully automated installation
+    * DNS-based cluster identification
+    * Self-healing: everything runs in Auto-Scaling Groups
+    * Limited OS support (Debian preferred, Ubuntu 16.04 supported, early support for CentOS & RHEL)
+    * High availability (HA) support
+    * The ability to directly provision, or generate terraform manifests
+
+  You can also build your own cluster using [`kubeadm`](#term-kubeadm) as a building block. `kops` builds on the kubeadm work.
