Shirako

Yo....I'm Shirako, I stumled upon this website and tool out of sheer curiosity to see if the switch could be modded and stuff, apparently it can now.....but I was wondering how and if anyone had any resources as to safely do it and get a bricked switch as that's always my biggest concern. Also how would I go about using this sites pokemon tool with the switch? Are there any resources available like how to install and what not? Please and thank you.
