 You may want to add **worker** nodes to your existing cluster. This can be done by re-running the `cluster.yml` playbook, or you can target the bare minimum needed to get kubelet installed on the worker and talking to your masters. This is especially helpful when doing something like autoscaling your clusters.

 Connecting to Kubernetes
 ------------------------
+
 By default, Kubespray configures kube-master hosts with insecure access to
 kube-apiserver via port 8080. A kubeconfig file is not necessary in this case,
-because kubectl will use http://localhost:8080 to connect. The kubeconfig files
+because kubectl will use <http://localhost:8080> to connect. The kubeconfig files
 generated will point to localhost (on kube-masters) and kube-node hosts will
 connect either to a localhost nginx proxy or to a loadbalancer if configured.
 More details on this process are in the [HA guide](ha-mode.md).

 Accessing Kubernetes API

 The main client of Kubernetes is `kubectl`. It is installed on each kube-master
 host and can optionally be configured on your ansible host by setting
-`kubeconfig_localhost: true` in the configuration. If enabled, kubectl and
+`kubectl_localhost: true` and `kubeconfig_localhost: true` in the configuration:

-see a list of nodes by running the following commands:
 
-    cd artifacts/
+-   If `kubectl_localhost` enabled, `kubectl` will download onto `/usr/local/bin/` and setup with bash completion. A helper script `inventory/mycluster/artifacts/kubectl.sh` also created for setup with below `admin.conf`.
-    ./kubectl --kubeconfig admin.conf get nodes
+-   If `kubeconfig_localhost` enabled `admin.conf` will appear in the `inventory/mycluster/artifacts/` directory after deployment.
 
-If desired, copy kubectl to your bin dir and admin.conf to ~/.kube/config.
