Multi users with git
There's only one person on the server, but two more people have joined the project. Is there a question of how to do that when they work with the website, they only work with their branches? That's what if the laser cuts through the ftp, he's active in his branch. And for the admin, for example, the silence of the master's branch.
It's not clear how work is related.
FTP♪ You'd have to study the match, the basis.
For example, if you need to distribute the work of the developers, you can use that approach. Established
bareRepositories (bottomless, unfilled) and cloned by development directories + test site + sold.
Each developer works with any branch in its directory and when the task is ready
git mergee.g. test or master and
git pushin remote repositories and then on the test site or sale respectively
git pullwith remote repository.
