+=========================
+DNF system-upgrade Plugin
+=========================
+
+-----------
+Description
+-----------
+
+DNF system-upgrades plugin provides three commands: ``system-upgrade``, ``offline-upgrade``, and
+``offline-distrosync``. Only ``system-upgrade`` command requires increase of distribution major
+version (``--releasever``) compared to installed version.
+
+``dnf system-upgrade`` can be used to upgrade a Fedora system to a new major
+release. It replaces fedup (the old Fedora Upgrade tool). Before you proceed ensure that your system
+is fully upgraded (``dnf --refresh upgrade``).
+
+The ``system-upgrade`` command also performes additional actions necessary for the upgrade of the
+system, for example an upgrade of groups and environments.
+
+--------
+Synopsis
+--------
+
+``dnf system-upgrade download --releasever VERSION [OPTIONS]``
+
+``dnf system-upgrade reboot``
+
+``dnf system-upgrade clean``
+
+``dnf system-upgrade log``
+
+``dnf system-upgrade log --number=<number>``
+
+``dnf offline-upgrade download [OPTIONS]``
+
+``dnf offline-upgrade reboot``
+
+``dnf offline-upgrade clean``
+
+``dnf offline-upgrade log``
+
+``dnf offline-upgrade log --number=<number>``
+
+``dnf offline-distrosync download [OPTIONS]``
+
+``dnf offline-distrosync reboot``
+
+``dnf offline-distrosync clean``
+
+``dnf offline-distrosync log``
+
+``dnf offline-distrosync log --number=<number>``
+
+-----------
+Subcommands
+-----------
+
+``download``
+ Downloads everything needed to upgrade to a new major release.
+
+``reboot``
+ Prepares the system to perform the upgrade, and reboots to start the upgrade.
+ This can only be used after the ``download`` command completes successfully.
+
+``clean``
+ Remove previously-downloaded data. This happens automatically at the end of
+ a successful upgrade.
+
+``log``
+ Used to see a list of boots during which an upgrade was attempted, or show
+ the logs from an upgrade attempt. The logs for one of the boots can be shown
+ by specifying one of the numbers in the first column. Negative numbers can
+ be used to number the boots from last to first. For example, ``log --number=-1`` can
+ be used to see the logs for the last upgrade attempt.
+
+-------
+Options
+-------
+
+``--releasever=VERSION``
+ REQUIRED. The version to upgrade to. Sets ``$releasever`` in all enabled
+ repos. Usually a number, or ``rawhide``.
+
+``--downloaddir=<path>``
+ Redirect download of packages to provided ``<path>``. By default, packages
+ are downloaded into (per repository created) subdirectories of
+ /var/lib/dnf/system-upgrade.
+
+``--distro-sync``
+ Behave like ``dnf distro-sync``: always install packages from the new
+ release, even if they are older than the currently-installed version. This
+ is the default behavior.
+
+``--no-downgrade``
+ Behave like ``dnf update``: do not install packages from the new release
+ if they are older than what is currently installed. This is the opposite of
+ ``--distro-sync``. If both are specified, the last option will be used. The option cannot be
+ used with the ``offline-distrosync`` command.
+
+``--number``
+ Applied with ``log`` subcommand will show the log specified by the number.
+
+-----
+Notes
+-----
+
+``dnf system-upgrade reboot`` does not create a "System Upgrade" boot item. The
+upgrade will start regardless of which boot item is chosen.
+
+The ``DNF_SYSTEM_UPGRADE_NO_REBOOT`` environment variable can be set to a
+non-empty value to disable the actual reboot performed by ``system-upgrade``
+(e.g. for testing purposes).
+
+Since this is a DNF plugin, options accepted by ``dnf`` are also valid here,
+such as ``--allowerasing``.
+See :manpage:`dnf(8)` for more information.
+
+The ``fedup`` command is not provided, not even as an alias for
+``dnf system-upgrade``.
+
+----
+Bugs
+----
+
+Upgrading from install media (e.g. a DVD or .iso file) currently requires the
+user to manually set up a DNF repo and fstab entry for the media.
+
+--------
+Examples
+--------
+
+Typical upgrade usage
+---------------------
+
+``dnf --refresh upgrade``
+
+``dnf system-upgrade download --releasever 26``
+
+``dnf system-upgrade reboot``
+
+Show logs from last upgrade attempt
+-----------------------------------
+
+``dnf system-upgrade log --number=-1``
+
+--------------
+Reporting Bugs
+--------------
+
+Bugs should be filed here:
+
+ https://bugzilla.redhat.com/
+
+For more info on filing bugs, see the Fedora Project wiki:
+
+ https://fedoraproject.org/wiki/How_to_file_a_bug_report
+
+ https://fedoraproject.org/wiki/Bugs_and_feature_requests
+
+Please include ``/var/log/dnf.log`` and the output of
+``dnf system-upgrade log --number=-1`` (if applicable) in your bug reports.
+
+Problems with dependency solving during download are best reported to the
+maintainers of the package(s) with the dependency problems.
+
+Similarly, problems encountered on your system after the upgrade completes
+should be reported to the maintainers of the affected components. In other
+words: if (for example) KDE stops working, it's best if you report that to
+the KDE maintainers.
