Replacing '93 Headlight Bulbs.......HELP!!!!!

Can someone please help me????? I need help replacing a headlight bulb on the passenger side of my '93 Grand Am. Is this something fairly simple to do? The high beams both work; it's one of the low beams that is out. I don't have a manual so I can't look in that. Do I have to take out the whole headlight assembly or do you just unscrew the "thing" holding the bulb and pop it out?

Just grab it from behind and twist it and i pops out, but if you don't haave small hands it's kind of annoying, I just grab the wire and pull on it a little to twist the bulb loose, then it just pops right out then there's a little clasp you have to pop up to pull the blulb out and if you have a little trouble getting it out (for space reasons) it will take a little bit longer to get it back in.
