About Syncing projects

Hi!
I would like to know if there is a video what i can follow to sync my project with my teammate.
I have looked in youtube but havent found any videos which include revision control setup and extensive multi user editing setup.
Ive tried many ways but i need one video.
Could anyone help me with this??
This question is also for the developers of unreal engine because i think that there should be some official videos from unreal engine for how to sync projects (full guide).
Im patiently waiting for answer!
Thank you, in advance for those who help me fix this problem.
