The commits represent the changes that have been made. A commit can be understood as a photo of a Sketch file at some point in time, allowing us to return to it whenever we want to. The set of commits form a log, which reflects all the changes made to the various Sketch files that comprise the project. This allows us to have full awareness of the work carried out, and that in the event of any unforeseen absence, the work can continue without any problem. Any member of the team could continue without any loss of information, knowledge, and work.
