I've documented what I do for a two sided board, if your doing a single sided then simple drop the steps for alignment and protecting each side. Note when handling ANY chemicals I recommend you use gloves and safety glasses.

I typically use a 16 pin connection and use the 8pin double row pitch 2.54mm double-spaced straight pin male IDC socket box header connector as it shrouds the pins and minimizes the possibility of a reversed connection that could destroy the board.
