If you are a new bee keeper and do not have a mentor I suggest you look at YouTube for methods of installing your bee package. I typed in "Bee Package Installation" into the YouTube search engine and it immediately came back with 140 videos (7 pages X 20 videos per page) about installing package bees. Remember that if you ask 10 beekeepers a bee related question you will get 10 different answers to your question. Its the same with installing a bee package. Many methods and each has its own advantages and disadvantages.
Get a mentor to help you the first time if you can. Otherwise, watch the videos and do it yourself. Its not rocket science. Just wear a veil to protect your head, go slow step by step, and you won't have a problem. Its just a little intimidating the first time you confront those 10,000 bees in the package.
