wikiHow: collaborative how-to knowledge base

Structure and features

Most articles follow a consistent how-to format: a short summary of the goal, a list of required items or warnings when relevant, and an ordered sequence of steps. Many pages include images, diagrams, tips, and troubleshooting sections. The platform has used the open-source MediaWiki engine or derivatives of it for site software, and it maintains article histories so edits can be reviewed and reverted when necessary.

History and scale

The project began as a focused effort to assemble practical guidance into a centralized resource and expanded over time through contributions and editorial oversight. By the mid-2010s the site had grown to hundreds of thousands of articles and attracted millions of readers. For example, as reported in 2017 wikiHow hosted a large corpus of free how-to pages and a substantial registered community of editors.

Community and quality control

Content is produced by a mix of volunteer authors, community editors and paid staff who enforce style, accuracy and readability standards. The site uses policies and editorial workflows to reduce errors and bias, including peer review, revision histories and flags for disputed material. This combination of crowd-sourced writing and centralized moderation helps balance wide coverage with consistent presentation.

Uses and examples

People consult the site for practical guidance on topics ranging from household repairs and cooking to technology, personal finance and professional skills. Educators, hobbyists and DIY enthusiasts often use articles as quick references or starting points to learn basic techniques. Organizations sometimes link to or adapt material for training and outreach, while individuals rely on concise how-to steps for immediate tasks.

Notable aspects and distinctions

• Focus on actionable instructions rather than encyclopedic background.
• Consistent article templates to aid clarity and usability.
• Combination of community editing with staff oversight to manage quality.
• Content available in several languages and covering a wide range of everyday topics.
