Contributing to MDN

MDN Web Docs needs your help! We have a large number of typos to fix, examples to write, bugs to fix, people to talk to, and more, and the number is growing as more people start using the site. This page outlines what you can do to help.

If you haven't contributed to MDN previously, the Getting Started guide can help you pick a task to jump in and help with.

What can I do to help?

There are multiple avenues you can take to contribute to MDN depending on your skillset and interests. Along with each task we provide a short description and an approximate time that each type of task typically takes.

If you are not sure what to do, you are always welcome to ask for help.

Primary contribution types

The links in this section lead to detailed guides explaining how to do a particular contribution task that we are most interested in getting community help with, either because they are a critical function, and/or because they have a large backlog associated with them. Please consider helping out with these tasks before you consider contributing in other ways.

Note: If you have found something that is incorrect on MDN but you're not sure how to fix it, you can report problems by filing a documentation issue. Please give the issue a descriptive title. (It's not helpful to say "Dead link" without saying where you found the link. Pro tip: Most "dead links" on MDN are to articles that haven't been written yet.)
