 # Introduction
+
 This is a basic library/wrapper for digital vehicle state safety/emissions inspection record lookups. If you need to check the last date(s) a vehicle was state inspected, and you know the state, this library is for you. A few states also support returning information on the last emissions/smog test. Originally designed for integration within a automotive service management SaaS application.
