+---------------------------------------------------------
+A tool to create a root file system for distro containers
+---------------------------------------------------------
+
+:Manual section: 1
+:Manual group: Virtualization Support
+
+.. contents::
+
+SYNOPSIS
+========
+
+
+``virt-create-rootfs`` [*OPTION*]
+
+
+DESCRIPTION
+===========
+
+The ``virt-create-rootfs`` program is a shell script setting up a root file
+system for a distribution container.
+
+The basic structure of most virt-create-rootfs usage is:
+
+  ``virt-create-rootfs`` -r /path/to/root -d distro-name
+
+
+OPTIONS
+=======
+
+``-h``, ``--help``
+
+Display command line help usage then exit.
+
+``-r``, ``--root``
+
+Set the path where to create the new root file system.
+
+``-d``, ``--distro``
+
+Set the name of distribution to use for the root file system.
+
+As of now, only SLED-<XXX>, SLES-<XXX> and openSUSE-<XXX> are implemented
+where <XXX> is the version number. Examples are openSUSE-15.3, openSUSE-tumbleweed,
+and SLES-15.3. Note that SUSEConnect is required to handle SLE distributions.
+
+``-a``, ``--arch``
+
+Set the target architecture of the root file system to either i586 or x86_64.
+
+``-c``, ``--regcode``
+
+Set the registration code for the product to install in the root file system.
+For SLE distributions, use a registration code from SUSE Customer Center.
+
+``-u``, ``--url``
+
+For SLE distributions, set the registration server to use.
+Default: http://scc.suse.com.
+
+``--dry-run``
+
+Don't do anything, just report what would be done.
