Work flow for multiple developers

Using Git for theme code/plugins could be a good option while you can use a common db in order to be sure that you all have the same data entry.
This way you can easily update everyone local repository or review past code and you can keep relating with your collaborators without expecting different layout views and execution results.

You also don’t need to change wp-config.php settings after the first-time(You shouldn’t git it since it contains db user and pwd credentials).

Hope it helps!
