-  Pause Kubernetes
+  pause the Kubernetes control plane or other namespaces
 ---
 
+### Overview
+
+The pause command allows you to freeze containers using the Linux [cgroup freezer](https://www.kernel.org/doc/Documentation/cgroup-v1/freezer-subsystem.txt). Once frozen, processes will no longer consume CPU cycles, but will remain in memory.
+
+By default, the pause command will pause the Kubernetes control plane (kube-system namespace), leaving your applications running. This reduces the background CPU usage of a minikube cluster to a negligable 2-3% of a CPU.
 
 ### Usage
 
 ```
-minikube unpause [flags]
+minikube pause [flags]
