I recently became a beekeeper and it has been a fascinating hobby.  I love those little insects.  Here is a picture of one of my frames with my queen!

After doing a lot of research and watching almost every online video on the subject, my advice to you if you are getting into it is to purchase a professional course.  There is a lot of bad information out there from some well intentioned but inexperienced beekeepers.  There is a lot to know and you keep learning as you go.  A good place to start is Beekeeping 101, by Nick Winters.  He has a guide available online that is very inexpensive and comes with a lot of free extras.  You can purchase his course by clicking here:  http://c2c0b8mhkf-23zdb-4e-zawm4l.hop.clickbank.net/
