Git can be defined as an open-source distributed version control system tool. It is free and can handle projects of virtually any size quickly and accurately. It owes its creation to Linus Torvalds, who did it in 2005 in the process of developing Linux Kernel. In terms of the core parameters needed for a tool, Git has it all: it is functional; it performs well, is secure and flexible. In other words, it has what is needed by most teams and individual developers.
Using Git, teams can work seamlessly and synchronously, with all the team members being able to use the same files.
Yet, Git can make all this happen without confusion at any user’s end when more than one person is working on the same files for editing.
There are many ways it can be set up and configured, but at my job, here’s how we use it: when a new employee starts, he downloads all the files from GitHub, which is an online service we’re all connected to.
