-`yafti` is the uBlue firstboot installer, and it's configuration can be found in `/etc/yafti.yml`. You can look at what's done in the config and modify it to your liking.

+`yafti` is the uBlue "first boot" installer. It shows up the first time a user logs into uBlue. By default, the menu also shows up again anytime the image's yafti configuration differs from the user's last encounter, so feel free to expand or modify your custom image's yafti configuration over time. Your users will then see the yafti menu again after the OS update, and will be given a chance to install any new additions.
 
-The files `/etc/profile.d/ublue-firstboot.sh` and `/etc/skel.d/.config/autostart/ublue-firstboot.desktop` set up `yafti` so that it starts on boot, so if you wish to retain that functionality those files shouldn't be touched.
