Wikiversity is a Wikimedia Foundation project that supports learning communities, their learning materials, and resulting activities. It differs from Wikipedia in that it offers tutorials and other materials for the fostering of learning, rather than an encyclopedia. It is available in many languages.

The Wikimedia Foundation, Inc., abbreviated WMF, is an American 501(c)(3) nonprofit organization headquartered in San Francisco, California, and registered there as a charitable foundation. It is the host of Wikipedia, the seventh most visited website in the world. In addition, the foundation hosts 14 other related content projects. It supports the development of MediaWiki, the wiki software that underpins them all.
