You charge it, then link it with your phone, then play anywhere you want (It does not need a computer to use it). It comes pre-installed with a few demos to get you started. There is a lot of free games in the store. I also bought a Link Cable and can connect the Quest 2 to my PC to play PC VR games as well. It works great and the clarity of the screen is awesome! The controls are super responsive and easy to get used to.
