 # Container Linux Update Operator
 
-More aptly named "Container Linux Reboot Coordinator".
+The [Container Linux Update Operator](https://github.com/coreos/container-linux-update-operator) (i.e. CLUO) coordinates reboots of auto-updating Container Linux nodes so that one node reboots at a time and nodes are drained before reboot. CLUO enables the auto-update behavior Container Linux clusters are known for, but does so in a Kubernetes native way.
+
+## Create
+
+Create the `update-operator` deployment and `update-agent` DaemonSet.
+
+```sh
+kubectl apply -f addons/cluo -R
+```
+
+## Usage
+
+`update-agent` runs as a DaemonSet and annotates a node when `update-engine.service` indiates an update has been installed and a reboot is needed. It also adds additional labels and annotations to nodes.
+
+```
+$ kubectl get nodes --show-labels
+...
+container-linux-update.v1.coreos.com/group=stable
+container-linux-update.v1.coreos.com/version=1465.6.0
+```
+
+`update-operator` ensures one node reboots at a time and that pods are drained prior to reboot.
+
+!!! note ""
+    CLUO replaces `locksmithd` reboot coordination. The `update_engine` systemd unit on hosts still performs the Container Linux update check, download, and install to the inactive partition.

 # Kubernetes Dashboard
 
-!!! bug "In Progress"
+The Kubernetes [Dashboard](https://github.com/kubernetes/dashboard) provides a web UI to manage a Kubernetes cluster for those who prefer an alternative to `kubectl`.
-    These docs haven't been completed yet.
+
+## Create
+
+Create the dashboard deployment and service.
+
+```
+kubectl apply -f addons/dashboard -R
+```
+
+## Access
+
+Use `kubectl` to authenticate to the apiserver and create a local port forward to the remote port on the dashboard pod.
+
+```sh
+kubectl get pods -n kube-system
+kubectl port-forward POD [LOCAL_PORT:]REMOTE_PORT
+kubectl port-forward kubernetes-dashboard-id 9090 -n kube-system
+```
+
+!!! tip
+    If you'd like to expose the Dashboard via Ingress and add authentication, use a suitable OAuth2 proxy sidecar and pick your favorite OAuth2 provider.

 # Heapster
 
-!!! bug "In Progress"
+[Heapster](https://kubernetes.io/docs/user-guide/monitoring/) collects data from apiservers and kubelets and exposes it through a REST API. This API powers the `kubectl top` command and Kubernetes dashbard graphs.
-    These docs haven't been moved over yet.
+
+## Create
+
+```sh
+kubectl apply -f addons/heapster -R
+```
+
+## Usage
+
+Allow heapster to run for a few minutes, then check CPU and memory usage.
+
+```sh
+kubectl top node
+kubectl top pod
+```
+
