# Version Control

## What is VCS?

A version control system (VCS) or software configuration management (SCM) is a program or set of programs that track changes to a collection of files. 

Goals :

* easily recall earlier versions of individual files or of the entire project.
* allow several team members to work on a project, even on the same files, at the same time without affecting each other's work.

*A system that helps developers to keep track of multiple versions of something.*
