 ## Prepare the development POD

+This tutorial runs on a single-node CORD POD development environment.
+For best results, prepare a clean Ubuntu 14.04
 LTS installation on a server with at least 48GB RAM and 12 CPU cores.
+Update the packages to the latest versions.
 
-For step 1, use the single-node POD setup described at
-https://github.com/open-cloud/openstack-cluster-setup.  If you like, you can run
-[this script](https://github.com/open-cloud/openstack-cluster-setup/blob/master/scripts/single-node-pod.sh) to perform steps 1 and 2:
+To set up the POD, run
+[this script](https://github.com/open-cloud/openstack-cluster-setup/blob/master/scripts/single-node-pod.sh)

-ubuntu@pod:~$ bash single-node-pod.sh
+ubuntu@pod:~$ bash single-node-pod.sh -e

-[this script](https://github.com/open-cloud/openstack-cluster-setup/blob/master/scripts/compute-ext-net-tutorial.sh)
-inside the nova-compute VM.  It enables routing packets between the ExampleService and vSG subnets on a
-single-node POD.
+> NOTE: The above script can also automatically perform (nearly) all the steps of this
+> tutorial if run as `bash single-node-pod -e -t`.  However, you will still need 
+> to manually log into XOS and create an ExampleTenant, as described under 
+> [Configure ExampleService in XOS](#configure-exampleservice-in-xos)
+> below.  The script will tell you when it's time to do this.

+### Logging into XOS on CloudLab (or any remote host)
+
+The XOS service is accessible on the POD at `http://xos/`, but `xos` maps to a private IP address
+on the management network.  If you install CORD on CloudLab 
+you will not be able to directly access the XOS GUI.
+In order to log into the XOS GUI in the browser on your local machine (desktop or laptop), 
+you can set up an SSH tunnel to your CloudLab node.  Assuming that 
+`<your-cloudlab-node>` is the DNS name of the CloudLab node hosting your experiment,
+run the following on your local machine to create the tunnel:
+
+```
+$ ssh -L 8888:xos:80 <your-cloudlab-node>
+```
+
+Then you should be able to access the XOS GUI by pointing your browser to
+`http://localhost:8888`.  Default username/password is `padmin@vicci.org/letmein`.
