Git provides essential version control for developers managing code changes. Instead of a single file copy, Git creates a history of snapshots called commits, allowing users to revisit, compare, or restore past versions of a project.

The system offers safety through automatic backups, detailed tracking of who changed what and when, and supports seamless collaboration. Teams can work together without overwriting each other’s work, thanks to Git’s merging tools and commit history.

Local repositories live on your computer, while remote repositories like GitHub enable sharing and teamwork. You push changes from local to remote using `git push`, and pull updates with `git pull` to stay current.

Getting started requires installing Git, setting up SSH keys, and initializing a repository. Commands like `git add`, `git commit`, and `git status` help manage changes before syncing with the remote server.
