Open up two stops. When you meter the lightest value you want detail in, the meter will give you a reading for that area to be at zone V, i.e. middle grey. For that area to be white, with detail, you have to make it brighter, so you open up two stops from that reading. Basically, I put a paper zone scale on my meter, and whatever I meter for the highlights, I put on zone VII (7), which is two stops above middle grey.
