Write up and materials?

Is there a write up of this system on the site?

Here are a few links giving you an overview of one motion shooting:

I personally use the one motion technique with my daughter and her 4th grade team. I will also teach it with my son or something very close (emulating Stephen Curry, which is very similar to the one motion technique).
