Git is a version control system that tracks code changes, letting developers work safely in teams. Instead of creating duplicate files, it records who changed what and when. This makes collaboration efficient and recovery from errors simple. You work in a repository on your local machine, then sync with a remote hub like GitHub.

To start, initialize a new project with `git init` or copy an existing one using `git clone`. Track changes by checking status with `git status`, staging files with `git add`, and saving snapshots with `git commit`. Always pull the latest updates from the remote repository before starting new work to prevent merge conflicts.

A typical daily workflow involves pulling code, writing your feature, staging changes, committing with a clear message, and pushing to the remote. View your history with `git log` and inspect differences with `git diff`. Common mistakes include forgetting to pull first or writing vague commit messages, but Git is designed to recover from errors safely.
