I can't imagine it being any different than any other type of car but basically, pull the wheels 20 degrees and zero the gauge.  Swing it around the other way 20 degrees, level the gauge and take your reading.   Camber is neutral checking.  Maybe your asking for something I've never done but that's a basic caster/camber read.
