+### Replication Controller Commands
+
+#### Run
+```
+kubecfg [options] run <image> <replicas> <controller-name>
+```
+
+This command creates a Kuberenetes ReplicaController object which creates `<replicas>` copies of the container named by `<image>`, the newly created ReplicaController is named `<controller-name>`
+
+##### Example
+
+```
+kubecfg -p 8080:80 run dockerfile/nginx 2 myNginxController
+```
+
+#### Resize
+```
+kubecfg [options] resize <controller-name> <new-size>
+```
+
+Changes the desired number of replicas, causing replicas to be created or deleted.
+
+##### Example
+```
+kubecfg resize myNginxController 3
+```
+
+#### Stop
+```
+kubecfg [options] stop <controller-name>
+```
+
+Stops a controller by setting its desired size to zero.  Syntactic sugar on top of resize.
+
+#### Remove
+```
+kubecfg [options] rm <controller-name>
+```
+
+Delete a replication controller.  Only works if the desired size of the controller is zero.
+
+### RESTful Commands
+Kubecfg also supports raw access to the basic restful requests.  There are four different resources you can acccess:
+
+   * `pods`
+   * `replicationControllers`
+   * `services`
+   * `minions`
+
+###### Common Flags
+   * -yaml : output in YAML format
+   * -json : output in JSON format
+   * -c <config-file> : Accept a file in JSON or YAML for POST/PUT
+   
+#### Commands
+
+##### get
+Raw access to a RESTful GET request.
+
+```
+kubecfg [options] get pods/pod-abc-123
+```
+
+##### list
+Raw access to a RESTful LIST request.
+
+```
+kubecfg [options] list pods
+```
+
+##### create
+Raw access to a RESTful POST request.
+
+```
+kubecfg <-c some/body.[json|yaml]> [options] create pods
+```
+
+##### update
+Raw access to a RESTful PUT request.
+
+```
+kubecfg <-c some/body.[json|yaml]> [options] update pods/pod-abc-123
+```
+
+##### delete
+Raw access to a RESTful DELETE request.
+
+```
+kubecfg [options] delete pods/pod-abc-123
+```
+
