Rigging for a human body?

I’m trying to rig a human body, but I’m not sure how to use ikas with soft, connected joints rather than really defined separate pieces. I’ve read that the Joan of Arc tutorial is very good for modeling in most systems but that the rigging is different, and so I was a little nervous about it. Does anybody know where I can find a tutorial for how to rig a human body in Blender?

This is a good start
