The WYSIWYG (what-you-see-is-what-you-get) editor that is offered by the Mozilla Developer Network Wiki makes it easy to contribute new content.  The MDN editor guide shows you how to use the editor, as well as some details of features that may improve your productivity. Please make sure you read (and are compliant with) the Mozilla Terms before editing or creating new pages.

The MDN style guide offers information about how to format and style the content itself, including our preferred grammar and spelling rules.

Creating and editing links
Links not only among many documents, but within a single document are a crucial component to any wiki, and MDN relies heavily on them. Fortunately, links are also very easy to create, even though there are lots of ways to make them!
Creating redirects
Sometimes you need to have a page that simply redirects to another page, or to a section of another page. This article describes how to create redirects.
MDN editor basics
Editing content on MDN is easy; you can use the built-in WYSIWYG editor to create, edit, and improve articles and other pages almost anywhere on the site.
Using source mode in the MDN editor
MDN's editor has a prominent button that gives you the ability to switch into source editing mode. In this mode, you see the underlying HTML for the body of the article you're editing. This guide will help you understand what you can do with this feature, what you should do with it, and, most importantly, what not to do.
Using the live sample system
MDN supports turning sample code displayed in articles into running samples the reader can look at in action. These live samples can include HTML, CSS, and JavaScript in any combination.
Working with images
It's frequently useful to include images in articles. Images may be screenshots, examples of what a rendering should look like, or SVG diagrams of program flow, for example. This article describes how to use images in MDN content.
Working with tables
Tables are a useful way to present information; this article covers how to create and maintain tables on MDN and when you should and should not use them.
