DLNA Server Mudi E750 C6

Got this great new addition to the stunning GL-iNet range all nicely firmwared up to 3.1, totally mobile because it has a built-in battery etc, but HELP, no way to install minidlna etc. This product would be a perfect DLNA server on a low-cost airline where there are no power points onboard, for me to share my movies with my family and friends,
Please, can anyone give this almost very happy newbie some advice or instruction on how to install any kind of DLNA server onto my Mudi box so that I can simply hook up my USB drive containing my movies.
Thanks for reading
Regards, Les
