 Metatron is a Ruby library for creating [Metacontroller](https://metacontroller.github.io/metacontroller/)-based custom Kubernetes controllers.
 
-The intention is to make it as easy as possible to use Ruby to manage [custom resources](https://kubernetes.io/docs/concepts/api-extension/custom-resources/) within your Kubernetes infrastructure. No Golang required!
+The intention is to make it as easy as possible to use Ruby to manage [custom resources](https://kubernetes.io/docs/concepts/api-extension/custom-resources/) within your Kubernetes infrastructure. No Golang required! Use simple, Rack-based controllers to provide the logic for your custom resources. Metatron templates provide a most Kubernetes boilerplate code for you, so you can focus on the logic that enables your custom resources to do what you need them to do.
