Click a tool from the palette (upper-right of the window) to select it. The Path tool lets you click-and-drag a pathway. (Try dragging a path over another path and see what happens!) The Walker tool lets you add a little fella to traverse your path(s), by clicking on the start of a path. The Stop tool lets you add a stop to slow down your walkers and give them a break. Enjoy!
