 This image is distributed in two flavours: Plasma and Gnome, they have the same applications, but some minor differentes in theming, and some adapted aplications for better system integration (like `qpwgraph` <-> `helvum`). You can install this image by either installing the (current netinstall) ISO in [Releases](https://github.com/atomic-studio-org/Atomic-Studio/releases) or by rebasing your system to one of them.
 
-You can use Jack-only images that do not have pipewire enabled by default and you can use hardened images that have less hardware compatibility but have much better security!
