If you have another hive body, put the package inside and on top of the hive body you are introducing them to. They will exit the package to join the queen and clustered bees below the inner cover. If you only have single hive bodys, pull some frames, hang the queen, and put the package in the open space created by pulling the frames. Again, they will leave the package to join the bees clustered with the caged queen. Leaving the packages on the ground as in the picture, you get lots of "lost" bees that don't survive the cold, or drift and you can get a very strong young colony, and a couple weak ones. They don't know where home is if you don't show em.
