+=== Finding a Tracking Service Provider
+
+If you do not know the tracking service provider of a package id, you can use
+the tracking_service helper method to get a Trackerific class that most likely
+will be able to track the given package id.
+
+  include Trackerific
+  tracking_service "183689015000001"    # => Trackerific::FedEx
+  tracking_service "1Z12345E0291980793" # => Trackerific::UPS
+  tracking_service "EJ958083578US"      # => Trackerific::USPS
+  tracking_service "unknown package id" # => nil
