You don't need to be able to code—or to write well—in order to be able to help MDN! We have lots of ways you can help, from reviewing articles to be sure they make sense, to contributing text, to adding sample code. In fact, there are so many ways to help that we have a Getting Started page that helps you pick tasks to do, based on your interests and how much time you have to spare!

You can also help by promoting MDN on your own blog or website.

Documentation and articles

MDN wiki documents have been prepared with the contributions of many authors, both within and outside the Mozilla Foundation. Unless otherwise indicated, the content is available under the terms of the Creative Commons Attribution-ShareAlike license (CC-BY-SA), v2.5 or any later version.

When reusing MDN content, you need to ensure two things:

  1. Attribution is given to the original content.

    Please attribute "Mozilla Contributors" and include a hyperlink (online) or URL (in print) to the specific wiki page for the content being sourced. For example, to provide attribution for this article, you can write:

    About MDN by Mozilla Contributors is licensed under CC-BY-SA 2.5.

    Note that in the example, "Mozilla Contributors" links to the history of the cited page. See Best practices for attribution for further explanation.

  2. Your reuse is published under the same license as the original content — CC-BY-SA v2.5 or any later version.

Code samples and snippets

Code samples added on or after August 20, 2010 are in the public domain (CC0). No licensing notice is necessary, but if you need one, you can use: "Any copyright is dedicated to the Public Domain. http://creativecommons.org/publicdomain/zero/1.0/".

Code samples added to this wiki before August 20, 2010 are available under the MIT license; you should insert the following attribution information into the MIT template: "© <date of last wiki page revision> <name of person who put it in the wiki>".

You can determine which license a code sample is available under by browsing through the article's history using the "History" option in the gear-shaped drop-down menu at the top-right corner of the screen. The easiest way to track this down is to find the most recent revision that occurred before August 20, 2010 and check if the sample is there. If it is, then it was added before the licensing changed and is available under the terms of the MIT license. If it is not there, or there are no revisions before the change, then it was added after the change and is in the public domain.


If you wish to contribute to this wiki, you must make your documentation available under the Attribution-ShareAlike license (or occasionally an alternative license already specified by the page you are editing), and your code samples available under Creative Commons CC-0 (a Public Domain dedication). Adding to this wiki means you agree that your contributions will be made available under those licenses.

Some older content was made available under a license other than the licenses noted above; these are indicated at the bottom of each page by way of an Alternate License Block.

No new pages may be created using alternate licenses.

Copyright for contributed materials remains with the author unless the author assigns it to someone else.

If you have any questions or concerns about anything discussed here, please contact the MDN administrators.

Amzeruy n MDN Web Docs

The MDN Web Docs (previously Mozilla Developer Network (MDN), previously Mozilla Developer Center (MDC), a.k.a. Devmo) project started in early 2005, when the Mozilla Foundation obtained a license from AOL to use the original Netscape DevEdge content. The DevEdge content was mined for still-useful material, which was then migrated by volunteers into this wiki so it would be easier to update and maintain.

The name was changed to MDN Web Docs in June 2017 — see The Future of MDN: A Focus on Web Docs for the rationale behind this decision.

You can find more history of MDN on our 10th anniversary celebration page, including an oral history by some of the people who were involved.
