adjust Y end stop on minion

if I home all and got to 0,0 the nozzle is off the bed how to I shift y origin to be 5.5

this may be a perspective thing, but in my mind the origin would ideally be front left side side of the bed . looking straight ahead at the printer they Y end stop and motor is to the right side. current origin, from this perspective, is back left corner.

do I have something set incorrectly? is it just preference ?
