Where can I get information on how to make a player model from a ragdoll?

As the tittle says, where can I get information on how to make a player model from a ragdoll?

Thanks in advance.

I was going to make a tutorial soon over this; should be posted in a few weeks.

That’s nice, but right now, do you know a place on the internet where I get information about it?

No, but assuming it’s on the Valve Biped, just decompile it with this and add the proper animations.
