Goal is to have screenshots, text and even a playthrough video that shows all secrets.
Naming scheme for screenshots is zipname_bspname_X where zipname is for example kinn_marcher (of kinn_marcher.zip), bspname is marcher (marcher.bsp) and X is the number of the secret (in normal progression if possible, choose your own number if irrelevant).
The naming scheme for the wiki URL is /secrets/zipname_bspname
