Git began development in 2005 after Linux developers stopped using a proprietary source control system. Git allows for distributed version control, with each local copy being a complete repository. Users can commit locally and then sync with remote servers. Git is now the most commonly used version control system. It can be installed locally on computers through various means depending on the operating system. While graphical tools exist, the command line is recommended to become familiar with scripting skills needed for DevOps. Git manages local repositories while GitHub is a product for collaborating with teams by saving files remotely.
