 # Reporting Issues
 
-**The issue tracker is not a support forum.** Unless you can provide precise *technical information* regarding an issue, you *should not post in it*. If you need support, first read the [FAQ](https://github.com/yuzu-emu/yuzu/wiki/FAQ) and then either visit our Discord server, [our forum](https://community.citra-emu.org) or ask in a general emulation forum such as [/r/emulation](https://www.reddit.com/r/emulation/). If you post support questions, generic messages to the developers or vague reports without technical details, they will be closed and locked.
