Once you're at the University, they'll be plenty of signs and people to direct you to the right place. Otherwise, everything is as listed on page 4 of the Student Handbook:

CHECK-IN PROCEDURES
During the check-in period you may move your personal belongings into your room. Signs will be posted designating unloading only areas. After unloading, follow signs to designated parking. At check-in you will receive your room key, access card, and identification button. You will also receive directions to local restaurants, if requested. Since there will be limited food service available on campus for lunch, you are encouraged to have lunch off campus before the Opening Ceremonies.
