What it does
Git is a distributed version control system for tracking changes to source code and other files. Developers can commit history locally, create branches, compare changes, and exchange work with a remote repository. The command-line tool and its official tutorial cover the core workflow, while repository hosting is provided by separate services.
Start with a local repository
The official tutorial creates a repository, adds files to the index, and records a first commit. From there, a developer can inspect history and create a branch for a change before merging it back. Git's distributed design keeps local history and branch work available without a network connection; collaboration begins when a remote repository is configured and changes are fetched or pushed.
A useful habit is to review the staged diff before recording a commit, especially when a working tree contains generated files or unrelated edits. Git is a version-control engine, not a hosting site or a graphical editor, so teams still choose their own review and repository-hosting workflow. The official source license is GPLv2.
Strengths
- Local commits and branches support offline work before sharing changes.
- The official tutorial explains a path from a new repository to collaboration and branch management.
- The project has a broad ecosystem of command-line tools and graphical clients.
Watch out for
- Repository hosting, code review, and issue tracking are separate choices rather than features of the Git command-line tool.
- The staged index adds a step between editing files and committing them, so users need to understand what is being recorded.
Best for
- Developers who need a distributed history for source code or other changing files.
- Teams choosing their own repository hosting and review workflow.
