This is good. Things have started.
Now you need to continue to be patient, and follow the cycling article. Test again on Day 7 to see if your nitrites are clearly over 2ppm. If so, add another dose (3ppm) and test every 2 days. Don't add ammonia before then, as it takes the nitrite colony a lot longer to get to a useful size, and you'll end up with too much nitrite in the tank, which can stall your cycle.
