There really is very much to it.
If using it on a fly rod then you need those little foam "strike indicators" (bobbers). You need larger ones, maybe even weighted, for spinning tackle. I use a 1 or 2 # leader when I fish this way for trout.
Depending on the water depth, you need anywhere from a 5-12' leader.
1/80 or 1/100 th ounce jigs work best for me.
I cast out and let the bait settle. With a fly rod I knit and pearl watching the float at all times. If it goes down I set the hook. With spinning gear a very very very slow retrieve watching the float.
