It is dead simple, just make sure you get one of the little jobbies that you slide down the right joycon rail to short the pins that you need shorted - you’ll be doing it often when you’re setting things up and you don’t want to be messing around with a bit of wire. I seriously doubt that you will brick anything, especially if you take your time and read everything through before you get started. These instructions should get you where you want to be.
