 Currently, using package layering creates a new "deployment", or bootable filesystem root.
 It does not affect your current root.
-This preserves rollback and the transactional model, but means that the system must be rebooted after a package has been layered.
-If you don't want to reboot your system for switching to the new deployment, you can use an experimental `rpm-ostree ex apply-live` command to update the filesystem to see changes from new deployment, but it's generally expected that you use package layering sparingly, and use `flatpak` and `dnf install` inside a `toolbox` etc.
+This preserves rollback and the transactional model, but means that the system must be rebooted after a package has been layered or updated.

 Package layering is generally done from the command line.
 However, the Software application does rely on it for installing a small number of apps that are currently difficult to install as Flatpaks.
