        <para>
            The flatpak config command shows or modifies the configuration of a flatpak installation.
            The following keys are supported:
        </para>
        <variablelist>
            <varlistentry>
                <term><varname>languages</varname></term>
                <listitem><para>
                   The languages that are included when installing Locale extensions.
                   The value is a semicolon-separated list of two-letter language codes,
                   or one of the special values <literal>*</literal> or <literal>all</literal>. If this key is unset, flatpak
                   defaults to including the <varname>extra-languages</varname> key and the current locale.

                <listitem><para>
                   This key is used when languages is not set, and it defines extra locale
                   extensions on top of the system configured languages. The value is a
                   semicolon-separated list of locale identifiers
                   (language, optional locale, optional codeset, optional modifier) as documented by
