 # Kueue
 
-Kubernetes-native Job Queueing
+Kueue is a set of APIs and controller for job queueing. It is a job-level manager that decides when 
+a job should start (as in pods can be created) and when it should stop (as in active pods should be 
+deleted). The main design principle for Kueue is to avoid duplicating existing functionality: autoscaling, 
+pod-to-node scheduling, job lifecycle management and advanced admission control are the responsibility of 
+core k8s components or commonly accepted frameworks, namely cluster-autoscaler, kube-scheduler and kube-controller-manager 
+and gatekeeper, respectively.
+
+[bit.ly/kueue-apis](https://bit.ly/kueue-apis) (please join the [mailing list](https://groups.google.com/a/kubernetes.io/g/wg-batch) to get access) discusses the
+API proposal and a high-level description of how it operates; while [bit.ly/kueue-controller-design](https://bit.ly/kueue-controller-design) presents the detailed design of the controller.
