<title>Description</title>
<para>
Copies the specified apps and/or runtimes <arg choice="plain">REF</arg>s onto the removable
media mounted at <arg choice="plain">MOUNT-PATH</arg>, along with all the dependencies and
metadata needed for installing them. This is one way of transferring flatpaks
between computers that doesn't require an Internet connection. After using
this command, the USB drive can be connected to another computer and
<command>flatpak install</command> will prefer to install from it rather than
the Internet if (a) each ref comes from a configured remote whose GPG keyring will be
used for verification and (b) the refs on the drive are at least as new as what's
available elsewhere (e.g. the Internet if you're online). For this process to work a
collection ID must be configured on the relevant remotes on both the source and
destination computers, and on the remote server.
</para>
<para>
On the destination computer one can install from the USB (or any mounted filesystem) the
same way you would install from the Internet, e.g. with
<command>flatpak install flathub org.gnome.Builder</command> or using a GUI.
</para>
<para>
Each <arg choice="plain">REF</arg> argument is a full or partial identifier in the
flatpak ref format, which looks like "(app|runtime)/ID/ARCH/BRANCH". All elements
except ID are optional and can be left out, including the slashes,
so most of the time you need only specify ID. Any part left out will be matched
against what is installed, and if there are multiple matches an error message
will list the alternatives.
</para>
<para>
By default this looks for both installed apps and runtimes
with the given <arg choice="plain">REF</arg>, but you can
limit this by using the <option>--app</option> or <option>--runtime</option> option.
</para>
<para>
All <arg choice="plain">REF</arg>s must be in the same installation (user, system, or other).
Otherwise it's ambiguous which repository metadata refs to put on the USB drive.
</para>
<para>
By default <command>flatpak create-usb</command> uses <filename>.ostree/repo</filename>
as the destination directory under <arg choice="plain">MOUNT-PATH</arg> but if you
specify another location using <option>--destination-repo</option>
a symbolic link will be created for you in <filename>.ostree/repos.d</filename>.
This ensures that either way the repository will be found by flatpak (and other
consumers of libostree) for install/update operations.
</para>
<para>
Unless overridden with the <option>--system</option>, <option>--user</option>, or <option>--installation</option>
options, this command searches both the system-wide installation
and the per-user one for <arg choice="plain">REF</arg> and errors
out if it exists in more than one.
