There are many tutorials on the net.....heaps. The trouble with so many is that you will learn the WRONG way to do things as it has no quality control. IF you can get just a few dollars try and get one from here, they are competitvely priced and have a high quality production focus. It might cost a few dollars initially but better to spend that extra dollar if you have it, on higher quality food.

I know its hard for some people to come up with the funds but try if you can.
