 for the install.  As mentioned above, install Ansible on the head node and check out this repository.
 
 The playbooks assume that a bridge called *mgmtbr* on the head node is connected to the management
-network.  Also there must be a DHCP server on the management network that can hand out IP addresses

+network.  Note that also there must be a DHCP server on the management network that can:
+ 1. hand out IP addresses to VMs
+ 2. resolve VM names to IP addresses on the head node

+If you need to set up `dnsmasq` to do this, 
 take a look at [this example](files/etc/dnsmasq.d/cord).
 Then follow these steps:
 
 * Edit *cord-hosts* with the DNS names of your compute nodes, and update the *ansible_ssh_user* variable appropriately.
-  Before proceeding, this needs to work on the head node: `ansible -i cord-hosts compute -m ping`
+  Before proceeding, this needs to work on the head node: `ansible -i cord-hosts all -m ping`
 * Run: `ansible-playbook -i cord-hosts cord-setup.yml`
 * After the playbook finishes, wait for the OpenStack services to come up.  You can check on their progress
