+		<title>Atomic Upgrade and Rollback via RPM-OSTree</title>
+		<para>
+			Fedora&nbsp;22 includes <application>RPM-OSTree</application>, a mechanism used on Fedora Atomic installations to perform atomic upgrades and rollbacks for the entire system (kernel as well as userspace).
+		</para>
+		<para>
+			Instead of performing a package-by-package installation and upgrade on each client machine, the tooling supports composing" sets of packages on a server side. Clients can then perform atomic upgrades as a tree.
+		</para>
+		<para>
+			On systems using <application>RPM-OSTree</application>, standard package managers (<application>DNF</application> and <application>Yum</application>) do not work normally; they can only be used in read-only mode.

+			<para>
+				The version of <application>RPM-OSTree</application> available in the default <systemitem>updates</systemitem> repository and on installation media will not work due to a known issue. To use this tool, enable the <systemitem>updates-testing</systemitem> <application>DNF</application> repository and update the <package>rpm-ostree</package> package.
