I run a notched inner cover with the rim up if it has a flat side to it. Hole in the middle for a quart jar. If you want an upper entrance just slide the outer cover forward and slid to the rear to close it off.
I believe it is best for the bees to have access to the area between the inner and outer cover for housekeeping, and with an entrance to boot they will go into this area.
