+To connect, add your private key and SSH into any client or server with
+`ssh ubuntu@PUBLIC_IP`. You can test the integrity of the cluster by running:
+
+  $ consul members
+  $ nomad server-members
+  $ nomad node-status
+
+If you see an error message like the following when running any of the above
+commands, it usuallly indicates that the configuration script has not finished
+executing:
+
+"Error querying servers: Get http://127.0.0.1:4646/v1/agent/members: dial tcp
+127.0.0.1:4646: getsockopt: connection refused"
+
+Simply wait a few seconds and rerun the command if this occurs.
+
+The Consul UI can be accessed at http://PUBLIC_IP:8500/ui.
