The most commonly used hive is a Langdtroth. They go in and out the bottom. There are frames (Pete is still building those) inside the boxes where the bees, build comb, lay larvae, and store honey. There is a lot going on in there. You really need to find a mentor and/or read a lot to learn the process.

If you just want pollinators there are simple nests you can build for orchard? bees which is another way to go. There is a bee keeping subreddit if you want to follow the trials and tribulations of others.
