Help with making custom UGC bundle

I’m trying to create a UGC bundle but I’m confused from the point I am currently at.

I have a character that is split in to the 15 parts, and I have a “cage” and “Armature”. I don’t know what to do now I am so confused. :sob:

The parts of my character (all 15 for r15)
If you know what to do next please tell me!
