GitHub Wiki
GitHub Wiki is a built-in documentation feature on GitHub that allows users to create and maintain project documentation directly within a GitHub repository. It uses Markdown for formatting and provides a simple, version-controlled way to document software projects, APIs, or other collaborative work. Wikis are stored as a separate Git repository within the project, enabling easy editing and tracking of changes.
Developers should use GitHub Wiki when they need lightweight, integrated documentation for their GitHub-hosted projects, such as open-source libraries, tools, or team workflows. It's ideal for creating user guides, API references, or contribution guidelines without external tools, as it leverages GitHub's familiar interface and version control. Use cases include documenting setup instructions, code examples, or project roadmaps to improve collaboration and onboarding.
