Team parking pass?

I just received an email from Ticletforce regarding a parking pass. It said the following:

** Hello!

Just a reminder that you bought tickets to:
VEX Robotics Championship (Volunteer Parking)
Parking - Volunteer / Team Parking

at Kentucky Exposition Center.
937 Phillips Lane , Louisville, KY 40209

See you at 5:59 AM on 04/20/2017! **

How do I actually GET the parking pass? Sorry for the dumb question.

Thanks!
