yes there is a one step... i actually just made a guide for it a few minutes ago. here it is:
Coffee Grinder Guide
it's all text, no pics or vids so it won't really show you what they look like but i tried to be as descriptive as possible. that video posted by odsca shows you what it is... i played it on mute so it might even teach you how to do it, but i don't know. i didn't watch all of the video either but the coffeegrinder is definitely in there. it basically just swinging your leg around your body while in a crouched position. coffee grinders are super easy too.
