The 4017 is just a decade counter, so the outputs will be energized one-at-a-time for each count, and it'll wrap when it counts past nine. You just have to figure out what pattern you want and arrange the diodes to match. The PDF appears to show a simple circuit that will "walk" the LED's back and forth as the counter counts.
