A version control system that tracks changes to your code over time.
Git is the world's most popular Version Control system. It tracks every change to your project, lets you undo mistakes, and enables team collaboration. Every professional developer uses Git daily.
Git works with commits (snapshots), branches (parallel development), and merges (combining work). Hosted on GitHub, Git repositories are the hub for collaboration. Git integrates with IDEs, code editors, terminals, CI/CD pipelines, and Deployment workflows.
Core Git operations include staging, committing, pushing, pulling, and branching. npm packages, environment variables files, and Docker configs are all tracked with Git. Claude Code uses Git directly, and SSH keys authenticate Git connections to remote servers. Hosting platforms auto-deploy from Git.
