 ## Usage
+The easiest way to bootstrap a cluster is to use the cluster recipe
+and use [Chef provisioning][8] which is a relatively new
+extension. This extension allows you to use any driver and easily
+stand up a cluster. Once the [Chef Development Kit][9] has been
+installed you can run the following command to provision a cluster.
+
+```ruby
+gem install chef-provisioning chef-provisioning-fog
+export CHEF_DRIVER=fog:AWS
+chef-client -z cluster.rb
+```
 
-### consul::default
+Please follow the [Chef provisioning README][10] which provides more
+detailed information about provisioning. You'll need to configure
+your credentials prior to provisioning.
