Bees - equipment
Clothing
I think most people are familiar with beekeeping clothing, protective all in one suits, smocks or jackets with mesh hoods to prevent bee stings. Gloves for those less experienced bee keepers, although plenty of experienced beekeepers go without. I'm definitely still wearing gloves.
If you're going to start beekeeping, I'd suggest you definitely need a hood, smock and gloves as a bare minimum. That's where I started. Although when I made a mistake in my first year of beekeeping and the bees got into the smock, I quickly upgraded to an all in one suit!
Tools
It's helpful to have have tools to pry out frames and clean the hives, a smoker helps keep the bees calm during inspections and a soft bee brush to gently encourage bees off anything you want. to inspect are alway useful.
Hives
It's pointless having suits or tools if you haven't got hives to house the bees. I use commercial hives. They're are several different types of hive but they mostly consist of similar components. A floor, a brood body to hold brood frames, a queen excluder, supers to hold frames for the honey, crown boards and a roof. That's the basics. There are all sorts of other components you'll eventually need, like bee escapes, and dummy boards. In the links you find more complete information about beehive equipment.
