+name: wksctl
+version: git
+summary: Open Source Weaveworks Kubernetes Subscription
+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
+confinement: devmode
