Best way of adding bones?

[HailFireer]

OK, so I use milkshape for mesh making and texture wrapping.
I also read tutorials on animation transfer, and I know how to get the names of the bones.

My problem is how to get them from boned to unboned model I made.
Or do I have to make bones my self. If so, what is easiest way to use. And how to figure out which bones i need if I am not going to use all animations (not using morphed anims in druid of the claw, demon hunter, etc.).

I looked through tutorials but found nothing. Sorry if I missed anything
