Right at the bottom is the Menu (Palette) containing all the programming blocks, the "language" you use to talk with the computer. To program a robot, you can drag and drop these programming blocks to the working area, the white area in the center (click on programming block, drag to working area in the center and let go). The very first block you should put in the working area is the START block
. To start a program going, you click on this START block.
