OK. I am on Mac, so installation and operation was a no-brainer.They point to a location on how to create scripts in order to get the daemon running under Linux. The only writeup I saw for Fedora was for the old Fedora 15, which is way, way, out-of-date. They also provide a package for QNAP, but provide zero operational instructions. The program may be good, but the documentation is extremely lacking (IMHO).
I use the console app exclusively for that.
BTW they have quite good Wiki https://wiki.serviio.org/doku.php
and Forum https://forum.serviio.org
