What is Git?

Git is a free and open-source version control system, which means that it is a tool for version control of project files. It mostly used by DevOps for source code management.

Why use a Version Control System(VCS)?

• Storing Versions - Saving a project version after making changes is necessary. But without version control system, all this becomes chaotic and cumbrous.

• Version Rollback - Being able to restore older versions of a file (or even the whole project) effectively is useful. But without version control system, this would be inefficient and compress the scope of attempts.

• Teamwork Friendly - Most projects are difficult to be completed by one person in a short period of time, so effective teamwork is essential. Without version control system, when a project requires teamwork to be completed, it cannot maximize the efficiency of teamwork.

• Understanding What Changed - With version control system, being able to see what exactly was changed in the file's content. This helps to have a better understanding of the project evolution between versions.

• Backup - With version control system, especially a distributed version control system like Git, which can act as a backup. When the server crashes, it can be recovered using one of teammates' Git repository.
