Beginning developers may wish to watch this intro video (slides) and browse the list of simple extensions when considering how to create a new extension. Some of the code from these extensions can provide insight into how to approach an implementation task, or even be cannibalized for your purposes.

License[edit]
You may want to include a licensing statement at the beginning of your extension file, e.g.:
/*
* @author Your Name <your@email.com>
* @copyright Copyright © 2012, Your Name
* @license http://www.gnu.org/copyleft/gpl.html GNU General Public License 2.0 or later
*/
Another way to do it is like this:
/**
* NameOfYourExtension
*
* Copyright © 2012 Your Name <your@email.com>
* https://www.mediawiki.org/
*
* This program is free software; you can redistribute it and/or modify

Extensions[edit]
- ErrorPage: Example of the page that uses extensions hooks DBConnectionErrorRaw and DBQueryErrorRaw for making nice error page.
- Example: This is an example extension. It doesn't actually do anything useful, but can be copied to provide the basis for your own extension.
- MyExtension FourFileTemplate: Four-file special page extension template.
- HelloWorld: A special page that says "Hello World!" in the appropriate language.
- Parser_hook: A parser hook example, use it on a page like
<hook arg1="foo" arg2="bar" ...>input</hook> - Variable_hook: An example parser hook that defines a new variable,
{{EXAMPLE}}
- Manual:Special_pages#Basic_special_page_template provides an example of a four-file Special Page extension called
MyExtensionthat outputs "Hello world!" Don't forget the standard collection of special pages in includes/specials, the functionality of some of which you may already be familiar with. - Assert Edit is a simple API extension.
- Awesomeness is a simple API and ArticleSave extension.
- BreadCrumbs (Kimon), which uses UserToggles, provides a good example of how to incorporate CSS files into your extensions.
- BypassSearch, which adds a user preference.
- CategoryGallery is a tag extension (e.g.
<categorygallery cat="Miley Cyrus"/>) that displays a gallery of all images in a category. - ChangeSessionSkin allows to switch between skins for the duration of the session, or until changed again, without changing the user preferences, thus available to anon users too.
- PatchOutput uses the OutputPageBeforeHTML hook to apply some patches to the HTML code of a page before it is displayed
- RemoveRedlinks uses the LinkBegin hook to turn all red links into regular text.
- ViewFiles implements a special page, Special:ViewFiles, to let users view the contents of files.
