        <para>
            This command creates a repository in MOUNT-PATH and pulls the given
            REF(s) into it so they can be found and pulled from (perhaps by another computer that's offline).
            See
            <citerefentry><refentrytitle>ostree-find-remotes</refentrytitle><manvolnum>1</manvolnum></citerefentry>
            for more information on P2P distribution.
        </para>
        <para>
            In order for ostree to pull refs from a mounted filesystem (such as
            a USB drive) the repo must be in a standard location. Specifically,
            subdirectories of <filename>.ostree/repos.d</filename> are checked,
            then <filename>.ostree/repo</filename>, <filename>ostree/repo</filename>,
            and <filename>var/lib/flatpak/repo</filename> are checked. By default
            <command>ostree create-usb</command> uses <filename>.ostree/repo</filename>,
            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>.
        </para>
        <para>
            This command will regenerate the <filename>summary</filename> file
            in the destination repo so that it stays accurate, so you shouldn't
            try to use summary signatures in the destination repo. This
            shouldn't be a concern because clients that support pulling from
            USB mounts use signed per-repo and per-commit metadata instead of
            summary signatures.
