The derailleur Hanger Alignment Gauge is relatively inexpensive (from $45 to $63, depending on where you purchase it, the DAG-2 from Park Tools). And with this issue, being a somewhat common problem, it would have been nice displaying instructions on how to use this simple tool.
good clear explanation, including what to do and not to do if you want instructions on using the park tool alignment gauge, try their website.
