i suck at explaining, so im gonna try my best....
you start by jumpin to the side a little, with your arms down and your legs up, spin your hips, and kinda fall to your left shoulder (collapse ccw). then you just split your legs and let the momentum take you, and link your mills
that explanation sucks ass, so go to this site, i think theres a clip where someone does a mill from standin
