I'm trying to rig a model to gmod and can't figure out how to rig it.

I tried following a tutorial on rigging a 3d model for use in gmod but since he used a model off of the workshop, it didn't fit my needs. I want to bring this model into gmod as a ragdoll but I can't seem to do it.

I don't need it to be a playermodel (like most tutorials are for), I just want a ragdoll to pose. I'm a noob at 3D modeling and coding and just want a simple ragdoll that nobody put on the workshop. If anybody is willing to port the model to gmod, I'd greatly appreciate it.
