Tutorial for 2 Persons Working on Same Project GitHub

Hello. My friend and I want to work on a project in Unreal 4 together. We live far away from each other.
I can’t setup a dedicated perforce server and want the simplest solution.

I tried to do github but I am totally confused.

Is it possible that someone could help me by making a tutorial on doing a new blank project and setting up Github from the start?
Video tutorial would be best!

Thanks a million.
