 Howard Roark, master architect and builder of AMIs.
 
 ## Overview
 
+Roark was built to solve the challenge of automating AMI builds across multiple AWS accounts and regions.
+
 * Roark builds AMIs from an Instance created by a Cloud Formation Stack.
 * Roark expects to be provided with a Cloud Formation Template that can be used to create this stack.
 * This template should create an Instance that is fully configured at bootstrap (via userdata, CloudInit, etc).
 * The stack must provide the ID of the Instance to be converted to an AMI (IE. i-1234abcd) as a Cloud Formation Output named **InstanceId**.
 * Once the stack is created, Roark will read the Instance ID from the Cloud Formation Output, stop the Instance, convert it into an AMI and destroy the stack.
