wikiHow is an online wiki-style publication featuring informational articles and quizzes on a variety of topics. Founded in 2005 by Internet entrepreneur Jack Herrick, its aim is to create an extensive database of instructional content, using the wiki model of open collaboration to allow users to add, create, and modify content. It is a hybrid organization, a for-profit company run for a social mission. wikiHow uses a forked version of the free and open-source MediaWiki software; these modifications made by wikiHow were freely available to the general public via a self-serve download site from 2010 to late 2020, when wikiHow chose to discontinue the self-serve portal, citing vague "DoS attacks", as well as noting that publishing the source code is "not part of our core mission".^[3][4][5] The site's text content is released under a Creative Commons NonCommercial license.

In February 2005, wikiHow had over 35.5 million unique visitors. As of December 2021^[update], wikiHow contains more than 235,000 how-to articles and over 2.5 million registered users.
