+> NOTE: This way of setting the development environment is sensibly more complex

 The official way of getting your environment up and running is by using
 [flatpak](http://flatpak.org/). For this you need to
 [install flatpak](http://flatpak.org/getting.html) on your system,
 along with flatpak-builder. Note flatpak-builder might be provided by an
 additional package on some distributions (such as Archlinux).
