You want to know how to get them into your game to work, or how to upload them somewhere so others can enjoy them?
Assuming you want to play them, Skyrim should read them if they're in the data folder, but I've never played outside of steam with a PC, so I don't know if you have the same little "Data Files" option, when you first start the game. If you do, click it and make sure the mods you wish to play are there and checked. Once done, they should load into the game. (Be careful uninstalling a mod, as it can corrupt your saves. Recommended to make a pre-emptive hard save, and delete everything after it when you've finished your test, so your next test/play starts right were you saved.
