 Here are some simple steps to get things rolling using the Heat templates:
 
-1. git clone https://github.com/larsks/heat-kubernetes/; cd heat-kubernetes
+1. Clone the repository:
+   ```
+   git clone https://github.com/larsks/heat-kubernetes/
+   cd heat-kubernetes
+   ```
+
+2. Create an appropriate image by running the get_image.sh script in this
+   repository.  This will generate an image called `fedora-20-k8s.qcow2`.
+   Upload this image to Glance.  You can also obtain an appropriate image from
+   https://fedorapeople.org/groups/heat/kolla/fedora-20-k8s.qcow2
+
+3. Create a file `local.yaml` with settings appropriate to your OpenStack
+   environment. It should look something like:
+   ```
+   parameters:
+     server_image: fedora-20-k8s
+     ssh_key_name: sdake

+
+     dns_nameserver: 8.8.8.8

+   You *must* provide settings for external_network_id and ssh_key_name; these
