 By default, the libvirt-coreos setup will create a single Kubernetes master and 3 Kubernetes nodes. Because the VM drives use Copy-on-Write and because of memory ballooning and KSM, there is a lot of resource over-allocation.
 
+There is both an automated way and a manual, customizable way of setting up libvert Kubernetes clusters on CoreOS.
+
+#### Automated setup
+
+There is an automated setup script on https://get.k8s.io that will download the tarball for Kubernetes and spawn a Kubernetes cluster on a local CoreOS instances that the script creates. To run this script, use wget or curl with the KUBERNETES_PROVIDER environment variable set to libvirt-coreos:
+
+```shell
+export KUBERNETES_PROVIDER=libvirt-coreos; wget -q -O - https://get.k8s.io | bash
+```
+
+Here is the curl version of this command:
+
+```shell
+export KUBERNETES_PROVIDER=libvirt-coreos; curl -sS https://get.k8s.io | bash`
+```
+
+This script downloads and unpacks the tarball, then spawns a Kubernetes cluster on CoreOS instances with the following characteristics:
+
+- Total of 4 KVM/QEMU instances
+- 1 instance acting as a Kubernetes master node
+- 3 instances acting as minion nodes
+
+If you'd like to run this cluster with customized settings, follow the manual setup instructions.

+#### Manual setup
