Mixxx has an unusually broad community for an open-source project, encompassing performing musicians, C++ addicts, amateur DJs, Internet radio broadcasters, and casual users. The Mixxx Wiki contains useful information for users, developers, and artists, and is summarized in the categories below.

Some pages have translations available. You can read them by clicking the language icon at the bottom of a page.

Most of the contents of this wiki can be edited by anyone, the main exception to this is the development roadmap which is a fairly authoritative description of the development team's plans. If you find outdated, incorrect, or incomplete information on this wiki, please fix it.

• Development builds: installers for the latest code we are working on. Please help us test the latest code and report bugs.

Do not upgrade to a new version without adequate time to test it before a performance.
