I'd like some help starting with avatar rigging please!

Heyo! Anyone able to link some good avatar-rigging tutorials? I am honestly not sure where to start. A lot of the ones I’ve found on youtube aren’t very helpful at all- or look very intimidating. Also a good starter-model would be nice! Also- should I use SDK2 , or SDK3 to start out? Thank you in advance!!

Hey there LuckyFox, I have a short guide I’ve made for friends if you’re interested, its not a video but a short visual guide I made to help grasp the basic understanding of how to rig anything. Let me know if you’d like to see it via DMs.
