You will hear people say "Github and Git are actually pretty simple". I thought that was a complete lie when started learning Git. I figured that they were just being elitist jerks in saying that : P.
So, Git offers a lot commands, and that is terribly confusing when just starting. But, it did turn out that, to do the basics with Git and work on projects, it really does just take a few commands to use Git.
The basic commands are:
push. But, you do have to use all of them more than 3 or 4 times to get how they all work.
A pretty good guide covering each topic can be found here, https://guides.github.com/activities/hello-world/.
