Best Resources to Learn Git

Git is a sophisticated, distributed version control system that can handle both small and large projects efficiently and easily. It is open-source and free. Git can be used to monitor changes in files and coordinate work among developers. It aims to promote data integrity, support for a disseminated, non-linear workflow, and speed.

What is Git?

Git is a free and open-source distributed version control system designed to handle everything from small to very large projects with speed and efficiency. It has an intuitive design which makes it easy for first timers, but still offers advanced features that are useful for experts. Git’s development began in 2005. The project was created out of frustration with the limitations of existing tools (such as CVS). In addition, Junio Hamano wanted to create a new product without having any formal software engineering experience. Git quickly became popular within Linux distributions because Linus Torvalds pushed its adoption there. As more companies started using it even outside the Linux world, various other products were built on top of or alongside git such as GitHub and Bitbucket.
