Pi3 built in Wifi and OSMC

Ok, I am very new to the Pi scene, I bought the Pi3 because it has built in Wifi. I installed NOOBS and the wifi works great. When I install OSMC, I cannot get the wifi to work. I was told to just install OSMC and not NOOBS but do not know how. Is there a users guide or something I can get for OSMC. How do I just intall OSMC and NOT NOOBS.

I have spent the past couple of hours trying to fix the Wifi but cannot get it figured out.

Please… any help would be greatly appreciated.
