+# DNS Horizontal Autoscaler
+
+DNS Horizontal Autoscaler enables horizontal autoscaling feature for DNS service
+in Kubernetes clusters. This autoscaler runs as a Deployment. It collects cluster
+status from the APIServer, horizontally scales the number of DNS backends based
+on demand. Autoscaling parameters could be tuned by modifying the `kube-dns-autoscaler`
+ConfigMap in `kube-system` namespace.
