-You will first need `python-sdbus-git` from the AUR (installable with your favourite AUR manager). 
+This is available on the AUR as `yabd-git`. You can install it with your favourite AUR helper, eg:
 
 ```console
-$ pikaur -S --asdeps python-sdbus-git # or your favourite AUR manager
-$ cd etc
-$ makepkg -si
+$ pikaur -S yabd-git
 ```
