Toyota: How do you take apart a headlight assambley?

can't figure out how to disassemble a headlight in my Camry (1995). A guy
in this forum got as far as the bulb itself, but I can't even get to that
point. Anyone here can tell me what i have to unscrew first to get this darn
headlight apart.
Thank you very much for any instructions you can provide.
