+## A Clustered Example
+
+We'll now look at a more complex example that better shows the
capabilities of Brooklyn.
+
+We'll start by deploying an application via YAML blueprint consisting of
the following layers.
+
+- A dynamically scalable Web App Cluster
+- A MySQL DB
+
+
+Copy the blueprint below into a text file, "mycluster.yaml", in your
workspace, but *before* you create an application
+with it, again modify the YAML to specify the location where the
application will be deployed.
+You will need at least five machines for this example, one for the DB, and
four for the tomcats
+(but you can reduce this by changing the "maxPoolSize" below.

This is a cut-and-paste error, it shouldn't have a location at all.
