        This is mostly useful if you use DNS challenges but Caddy does not
        currently support your provider.

        <emphasis>Note that this option does not create any certificates, nor
        does it add subdomains to existing ones – you will need to create them
        manually using <xref linkend="opt-security.acme.certs"/>. Additionally,
        you should probably add the <literal>caddy</literal> user to the
        <literal>acme</literal> group to grant access to the certificates.</emphasis>
