Take photos as you go along so you can reassemble correctly.
I don't have one in front of me, but it's really a matter of removing one part (usually a spring or pin) at a time carefully so that parts don't go "sproiiiing" across the room.
Write down the steps one at a time and then follow them backwards to reassemble.

If you are not confident that you can reassemble and adjust the safety and trigger function as they should - safely - get some help from your local gunsmith.
