-### I want a simple installation!
+### From distribution packages
 
-Understandable. Bismuth is a complex extension to KDE Plasma and therefore it
-requires complex packaging for different Linux distributions, at least for main
-ones: Ubuntu-based, Fedora-based and Arch-based. This is a complex task, so if
-you're skillful, you're welcome to create a package for your distribution and
-share it with others via PR to Bismuth.

+
+#### Arch-based distros
+
+Bismuth is available on AUR. Install the [`kwin-bismuth`
+package](https://aur.archlinux.org/packages/kwin-bismuth) with your favorite
+AUR helper.
+
+#### Other distributions
+
+If you are know a packaging solution for a distibution, that is not in this
+list, please provide a link to it via pull request.
