JAMMA is basically a wiring standard, meaning you use the JAMMA harness to connect all the audio, video, buttons & joysticks to your game source. Once this is done you can connect anything that is JAMMA based within minutes and be up and running. So with this being said, the main instruction needed, is the wiring diagram for the JAMMA harness. This is included in most manuals and is also found on the Internet in many places.
