WikiHow is a crowd-sourced how-to guide, powered by MediaWiki, the service that powers Wikipedia. Users put together steps, tips, and warnings on any topic, and other users can make additions or edits to those articles.
The service has more than 50,000 how-to articles, which are constantly being updated and edited. They're usually found in the results from major search engines, which has led to a steady month-by-month growth since the service launched in early 2005.
