Wait till late afternoon as sun is going down.
Dump 'em in. lol
No need to be fancy or anything to worry about.
Remove enuf TB's so one end is open, invert the pkg. into the hole and rap sharply so they all go in. If a few stragglers don't make it don't worry, just drop the container near the entrance and by dark they will find their way in.
I presume since you are a newbee that you wouldn't have any comb or anything laying around but don't worry it'll be just like them moving into a new tree. lol
Tape or tie or whatever the queen to a TB near the center so she is inside the hive and feed 1:1 sugar : water.
I just throw a couple of the frame style feeders so they sit on the bottom inside and let them bee for a couple of days. Any kind of feeder even the baggie in the bottom inside and then w/a razor knife put a few slits in it.
Check to make sure queen has been released in 2 days as she has been w/them for a few extra getting ready and on the trip to you. If not out then just dig away at a the candy plug till is only a little left and is holed (hole going right thru) If it takes another day for them to clean it out so she gets out n.p.
Zit poof and you are now a beekeeper. I'd continue feeding the 1:1 syrup till they won't want it anymore.
Cheers
