How to GIT
1.) Commit (make sure to select all you want to commit!)
2.) Pull (get the newest version from the server!)
3.) Push (transfer your work to the server!)

In case of an conflict you have two choices to solve the problem.

Revert corrupted files:
1.) Merded/Head -> last commit – SERVER
or
2.) Head -> your commit – LOCAL
