1)  You must turn your phone off when you go into the polling place.  As you come inside, you will see a table with several election workers.  Hand your photo ID to them and they will check you in using a computer.  They should ask  you your current address, and ask you to sign a computer screen.  They then will let you select a ballot for them to print for you. 

If you are not in their list of registered voters, are in the wrong polling place, or may have voted in the early election, they will help you get that problem worked out.

If you are physically challenged, have a language problem, or need someone--a member of your family or friend, or one of the election workers--to help you, tell the election worker.  They will help you.  It is your right as a voting citizen.
