Wikimedia is a global movement that promotes the sharing of free knowledge. It is best known for its flagship project, Wikipedia, an online encyclopedia that allows users to create and edit articles on a wide range of topics. The content on Wikipedia is collaboratively written and maintained by volunteers from around the world, making it a valuable resource for information. In addition to Wikipedia, the Wikimedia Foundation supports various other projects, including Wikimedia Commons, a repository of free media files, and Wiktionary, a collaborative dictionary. These projects aim to provide accessible knowledge and resources to everyone, regardless of their location or background.
