 # Autoscaling Special Interest Group
 
-Covers autoscaling of clusters, horizontal and vertical autoscaling of pods, setting initial resources for pods, topics related to monitoring pods and gathering their metrics (e.g. Heapster)
+Covers development and maintenance of componets for automated scaling in Kubernetes.  This includes automated vertical and horizontal pod autoscaling, initial resource estimation, cluster-proportional system component autoscaling, and autoscaling of Kubernetes clusters themselves.
