The Mixxx Wiki has a wealth of useful documentation for users and developers. New to it all and not sure how to get started? Checkout the Beginner DJ Links. Running into technical issues? See the Troubleshooting guide.
Have a Mixxx-related question? Something other DJs can help you with? Ask in the Mixxx Community Forums. This is also the place to find or share additional controller mappings, keyboard mappings, skin and script tweaks. You may also post your mixes and promote your upcoming gigs there.
Mixxx's Zulip chat instance is a fun place to hang out with the developers and meet some fellow DJs. Here, the Mixxx team discusses upcoming changes and programming related stuff. It can be used for support too. Join the discussion on the web or download the Zulip app and configure it to use the server mixxx.zulipchat.com.
The mixxx-devel mailing list (SourceForge and The Mail Archive archives) is now a low-traffic, mostly announcement channel. Subscribe if you would like to be informed about new releases and other topics.
Please report any bugs you find to our Bug Tracker. The bug tracker gives us a centralized place to pool our information on bugs, and prevents us from getting disorganized and forgetting about them.
