The history of MDN
Contributing to MDN
For ten years, the MDN community has been documenting the open Web. From fixing simple typos to writing entire suites of an entirely new API, everyone has something to offer and no contribution is too large or too small. We have over 90,000 pages of content that have been written or translated by members of our outstanding community of Mozillians. You can become one of them.
Whenever I want to know the "why" instead of the "how" MDN is the place to go.— Christian Heilmann
