Congrtats and you'll have fun. Just remember, once you start to pick them, they will regenearate. I usually pick 20% of a plant each week or so, somtimes sooner depending on the time of year. That way, you'll get "a lot" of peppers over the season.
When the first "mature" looking peppers appear, pick one and do a taste test. Usually, you will pick too soon and there really isn't much heat to them. So, just keep trying that unitl you get to the heat you're looking for and then start storing/cooking.
P.S. chicken poop is a great fertilizer and adds to heat.
