[feature request] document controllers.

I have a ton of controllers at my disposal, however documentation for adding them to the built in hard-coded list is abysmal. If I have a write-up I can add several controllers to the list

ps4 models not even recognized [yes! they are official controllers!]

Emulationstation does not have a controller DB - however it uses the LibSDL (libsdl.org) library to manage their configuration and detection. You might want to take a look at their controller database and amend that: http://hg.libsdl.org/SDL/file/0ef0e4cb7752/src/joystick/SDL_gamecontrollerdb.h

EDIT: Corrected.
