Git was developed by Linus Torvalds in 2005. Git is a distributed version control software. It is a widely used source code management system for software development. It is free and open source software(FOSS). It is useful for Programmers, Web developers, Project managers, Writers and many others. Anyone working with text files, sheets, design files, drawings, etc., can use Git to track versions.

Git manages the changes in documents, computer programs and web sites etc. It provides a historical record of what you have done over time. It allows developers to work collaboratively. In Git, conflicts can be easily resolved using the suggestions given by Git itself. If there is loss of data, it can be restored from any of the client repositories.
