What is a repository?
Simply speaking, think of a repository as a folder inside which files and sub-folders are stored. But it is actually more than that: It also stores earlier versions of the files in there too. When you use Git Winch usually you would create more than one repository – each one created to ensure that the members working on the files therein only handle just those files they need to work on, and not others. So the work of an office can be separated on a need-to-know basis. In case someone leaves the office, that person does not get the entire data of the office (which would have been the case if he/she was working without Git Winch!)
