+summary: Open Source Weaveworks Kubernetes System
+description: >
+  wksctl allows simple creation of a Kubernetes cluster given a set of IP addresses and an SSH key. It
+  can be run in a standalone environment but is best used via a GitOps approach in which cluster and
+  machine descriptions are stored in Git and the state of the cluster tracks changes to the descriptions.
+
+  Its features include simple creation of Kubernetes clusters, manage cluster and machine descriptions using Git,
+  manage addons like Weave Net or Flux, Sealed Secret integration
