This lab requires you to do simple steps to prepare for CS140. Many of you will already have done these steps and so don't need to do anything. For the rest of you, it is critical that you complete these steps by the time the first assignment goes out. Otherwise, it will be very difficult for you to stay on top of the other lab assignments.
