Welcome to the Mozilla Developer Network (MDN). Also known by its project name, "Devmo" (short for "DEVeloper.Mozilla.Org"), this site has been designed to be a comprehensive, usable, accurate, and valuable resource for web developers.
Please note that this wiki is for developer documentation only. Your cooperation is appreciated.

The Mozilla Developer Center (a.k.a. MDC, a.k.a. Devmo) project started in early 2005, when the Mozilla Foundation obtained a license from AOL to use the original 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.
Since then, the project has continued growing and now forms a central nexus for all developer documentation related to the Mozilla Project and open web technologies. In 2010, the name was changed to Mozilla Developer Network; 2011 saw the addition of Demo Studio for web developers to share and show off their code, and Learning pages to provide links to tutorials. (The name MDC lives on as "MDN Doc Center" for the documentation section.) In time, it is hoped that the Mozilla Developer Network will become a resource that web designers, application developers, and extension and theme writers visit on a regular basis.
