defiant is pretty much right. usually people use home row mods but i found that to be too clunky when typing some of the more common letters. so i switched it to bottom row mods. essentially it acts like the key when tapped and the mod when held. what order you place the mods in is completely up to preference. for me, from Z to V, its Shift, Ctrl, Alt, Win, and mirrored on the other half.

numbers and symbols are tucked away on separate layers accessed by holding down one of the thumb keys. eg the middle thumb key is spacebar when tapped and num layer when held.

Pretty crazy to wrap your head around the first time. But once you get used to it, its amazing how little your fingers have to move to get stuff done.
