Git ubuntu problems

Hey could anyone maybe write a tutorial on how to setup git server and client properly? i have done the tutorials of digital ocean but i cant seem to push back to server etc…

What im doing: I create a new folder (test) go to the folder then do git init i add some test files, add and commit them.

Locally i can clone the remote git but when i do changes and commit them locally and then try to push i get errors.

Anyone got any ideas?

Thanks!
