Making playlists

Hi,
Can anyone explain how to make (UPnP) playlists on Serviio (possible with free edition ?).
I'm talking about playlists that I could find on the renderer device while browsing contents on server (Serviio). When talking UPnP, after connection there all a set of folders (e.g. Image, Audio, Video, then for example for video: actor, director, ...). Well, for Audio there is a Playlist folder. I'd like to be able to build them and find them on my device
thanks
