# 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.* --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
