(request) Does Anyone Know How To Use Unreal Engine 4?

Hi guys! So I had this idea of turning my elementary school (Pretty small) into a map fit for some kind of FPS game. So, i installed Unreal Engine 4 a couple of days ago, everything is so complicated and all the YouTube tutorial videos are either out of date or unclear. If anyone of you know how to use the program and are willing to spare time to teach me how to use the program, please contact me on skype: tristanxvp. Any kind of help would be appreciated :) (By the way, my UE4 is version 4.10.2)
