OrangFACS is a standardized system that requires certification to use.
The OrangFACS Manual identifies each muscle movement that causes visible changes in facial appearance. These are called Action Units (AUs) and each AU is listed in the manual with a numerical code and several topics to aid understanding and clarification. These include the proposed muscular basis for the AU, a list of appearance changes, subtle differences between AUs and a comparison with FACS of other species. The manual contains pictures and videos throughout to aid training as well as a section related to broad muscular movements (Action Descriptors).
