 ## Breezy GNOME
+
 Breezy GNOME is a virtual workspace solution for Linux desktops that use the GNOME desktop environment (support GNOME versions 42 through 47); see [non-GNOME setup](#non-gnome-setup) if you want to try it without a GNOME desktop environment. It currently supports multiple virtual monitors and multiple physical monitors. See [upcoming features](#upcoming-features) for more improvements on the horizon.

 ### Steam Deck desktop mode
 
 Steam Deck's desktop mode runs KDE Plasma, so, for now, Breezy Desktop can only be run by launching a nested GNOME shell, and requires the read-only file system to be disabled to get setup. If you're interested, and *willing to accept any risks that come with disabling the read-only file system*, check out [the wiki entry](https://github.com/wheaney/breezy-desktop/wiki/Installing-on-Steam-Deck).
