Git Wiki
Git Wiki is a feature of Git-based platforms like GitHub, GitLab, and Gitea that allows developers to create and maintain project documentation directly within a repository using a wiki system. It typically uses Markdown or similar lightweight markup languages for content creation and is version-controlled alongside the codebase, enabling collaborative editing and tracking of documentation changes. This tool integrates documentation with the development workflow, making it easy to keep project guides, API references, and other documentation up-to-date.
Developers should use Git Wiki when they need to maintain project documentation that is closely tied to the codebase, such as setup instructions, contribution guidelines, or API documentation, as it ensures documentation evolves with the project. It is particularly useful in open-source projects or team environments where multiple contributors need to collaborate on documentation without complex tooling, as it leverages familiar Git workflows for version control and review. By using Git Wiki, teams can reduce documentation drift and improve accessibility, as the wiki is often hosted alongside the repository on platforms like GitHub.
