MDN Web Docs é uma plataforma de aprendizagem em evolução para as tecnologias da Web e software que energiza a Web, incluindo:

A nossa missão

MDN's mission is simple: to provide complete, accurate, and helpful documentation for everything about the open Web, whether it's supported by Mozilla-built software or not. If it's an open technology exposed to the Web, we want to document it.

In addition, we provide documentation about how to build and contribute to Mozilla projects and about Firefox OS and Web app development.

If you're not sure whether a particular topic should be covered on MDN, read: Does this belong on MDN?

Como é que pode ajudar

You don't need to be able to code—or to write—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.

Our community is a global one! We have amazing contributors all around the world, in a number of languages. If you'd like to learn more about us, or if you need help of any kind with MDN, feel free to check out our discussion forum or IRC channel !

Histórico da MDN Web Docs

MDN Web Docs (anteriormente Mozilla Developer Network (MDN), anteriormente projeto da Mozilla Developer Center (MDC), a.k.a. Devmo) começou no início de 2005, quando a Fundação Mozilla (inglês) obteve a licença da AOL para utilizar o conteúdo DevEdge original do Netscape. O conteúdo DevEdge foi minado para o material ainda útil, que foi migrado por voluntários para esta wiki, e assim esta seria mais fácil para atualizar e manter.

Pode encontrar mais história da MDN na nossa página de celebração do 10º. aniversário, incluindo uma história verbal por algumas das pessoas que estiverem envolvidas.
