+
+These are responsible for managing and running your containers on the cluster.  [Containers](#container-v1) are created
+by Controllers through [Pods](#pod-v1).  Pods run Containers and provide environmental dependencies such as shared or
+persistent storage [Volumes](#volume-v1) and [Configuration](#configmap-v1) or [Secret](#secret-v1) data injected into the
+container.
+
+The most common Controllers are:
+
+- [Deployments](#deployment-v1beta1) for stateless persistent apps (e.g. http servers)
+- [StatefulSets](#statefulset-v1beta1) for stateful persistent apps (e.g. databases)
+- [Jobs](#job-v1) for run-to-completion apps (e.g. batch jobs).
