Apple tv1 install help

Sorry I am a serious noob and do not have much of a clue of what I am doing. I put OSMC on a thumb drive and loaded to my apple tv1. If I take the thumb drive out of the apple tv it does not work anymore. Also it is somewhat useless because it will not allow me the option to connect to wifi. I do not have a wired connection available in this room. How do I connect to wifi, and can I load the program on the apple tv so I can operate without the thumb drive still in the apple tv?

Sorry if this is already answered here, I have done some looking and am only confusing myself more. Thanks for the help in advance!
