Document structures
Throughout MDN, there are various document structures that are used repeatedly, to provide consistent presentation of information in MDN articles. Here are articles describing these structures, so that, as an MDN author, you can recognize, apply, and modify them as appropriate for documents you write, edit, or translate.
Documentation processes
The MDN documentation project is enormous; there are a vast number of technologies we cover through the assistance of hundreds of contributors from across the world. To help us bring order to chaos, we have standard processes to follow when working on specific documentation-related tasks. Here you'll find guides to those processes.
Guide to the MDN editor UI
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.
Guidelines
These guides provide details on how MDN documentation should be written and formatted, as well as how our code samples and other content should be presented.
How-to guides
These articles provide step-by-step guides to accomplishing specific goals when contributing to MDN.
Localizing MDN
MDN is used by people all over the world as a reference and guide to Web technologies, as well as to the internals of Firefox itself. Our localization communities are a key part of the Mozilla project; their work in translating and localizing our documentation helps people around the world develop for the open Web. If you'd like to learn more about localization, or even start a new localization, this is the place to begin.
MDN and Persona sign-ins
Currently, MDN lets contributors sign in using two different authentication providers: Mozilla Persona and GitHub. Starting on November 1, 2016, we will remove Persona as an option for logging in. Therefore, you must enable Github authentication on your profile to avoid losing login access to MDN.
MDN tools
MDN offers a number of features that make it easier to track progress, manage content, and keep up with the latest changes to the site.
New Compatibility Tables Beta
You're probably here because you followed the beta notice link from one of our new compatibility tables. (No? Want to see the new tables? Make yourself a beta tester.)
