Introduction to Git | How Git Works

What is Git?

Widely known, as defined in Wikipedia, Git is a distributed version-control system for tracking changes in source code during software development. It was originally designed and developed by Linus Torvalds (creator of the Linux kernel) and is the most popular version control system to date.

It is equipped for enabling coordination work among programmers and data scientists, which can be used to track changes in any set of files. Its goals include speed, data integrity, and support for distributed and non-linear workflows.

Use more and Get comfortable

The shortest way to master Git is, to use it in projects. We recommend simulating a smaller group project, by creating files, naming it after the project, control branches and committing changes. Best practice includes adding an easy-to-understand commit messages. In a separate article, we will address naming convention for Git messages we use in projects at SHIFT ASIA.
