Wiki software is a type of collaborative platform that allows users to create, edit, and manage content collectively. It is designed to facilitate the sharing of knowledge and information, enabling multiple contributors to work together in real-time. Popular examples of wiki software include MediaWiki, which powers Wikipedia, and TikiWiki. These platforms typically feature a simple markup language for formatting text, making it easy for users to contribute without needing advanced technical skills. Wiki software often includes version control, allowing users to track changes and revert to previous versions if necessary, ensuring the integrity of the content over time.
