Where web enthusiasts learn, collaborate, and create
MDN’s strength comes from the passion and dedication of our global community. Since our founding in 2005, we’ve grown into a thriving network. Together, we’ve created a comprehensive, open, and free resource that serves web developers across the globe. With volunteers leading translation efforts in 7 languages, we’re truly international.
We are an open-source community dedicated to building resources for a better web. Our diverse contributors, including developers, technical writers, students, educators, designers, and more, come from various backgrounds and platforms. Anyone can contribute, and each contribution strengthens our community, driving innovation and improving this vital resource for developers worldwide.
There are many other things I like about MDN: the openness of its governance, the respect for contributors' work, the professional conversations, and the always timely reviews. MDN has consistently demonstrated the ideal form of an open-source project.

MDN Web Docs has the most up-to-date and accurate information and the content is presented in an easy-to-understand manner. I also like that it's available in many languages (very important!).
Yuji (MDN contributor)
There are millions of web developers in China, and many of them begin their developer journey at MDN Web Docs. Contributing to MDN Web Docs is an excellent way to help people who are starting out.
