Summary
Wikipedia is a free-content online encyclopedia written and maintained by a community of volunteers, known as Wikipedians, through open collaboration and the wiki software MediaWiki.
Wikipedia is the largest and most-read reference work in history, and is consistently ranked among the ten most visited websites; as of August 2024, it was ranked fourth by Semrush and seventh by Similarweb.
Founded by Jimmy Wales and Larry Sanger on January 15, 2001, Wikipedia has been hosted since 2003 by the Wikimedia Foundation, an American nonprofit organization funded mainly by donations from readers.

Reliability
If you do start with Wikipedia, you should make sure articles you read contain citations–and then go read the cited articles to check the accuracy of what you read on Wikipedia. For research papers, you should rely on the sources cited by Wikipedia authors rather than on Wikipedia itself.
The fact that Wikipedia is not a reliable source for academic research doesn’t mean that it’s wrong to use basic reference materials when you’re trying to familiarize yourself with a topic. In fact, the Harvard librarians can point you to specialized encyclopedias in different fields that offer introductory information. These sources can be particularly useful when you need background information or context for a topic you’re writing about.

MediaWiki
MediaWiki is free and open-source wiki software originally developed by Magnus Manske for use on Wikipedia on January 25, 2002, and further improved by Lee Daniel Crocker, after which development has been coordinated by the Wikimedia Foundation.
It powers several wiki hosting websites across the Internet, as well as most websites hosted by the Wikimedia Foundation including Wikipedia, Wiktionary, Wikimedia Commons, Wikiquote, Meta-Wiki and Wikidata, which define a large part of the set requirements for the software.
