Rigging a model for VRChat?

[Eternantium]

Apparently I have to do this for the model I want to use (my previous option's foot textures were unable to be put on right) and I am completely and totally confused & lost.

Get blender, import model, google how to rig in blender, rig model, then google vrchat custom avatars, get unity, and follow instructions for import. You may need to also understand decimation in blender if the model's poly count is high. Google that too. Good luck.
