UPDATE:   Locast2plex is still in beta and the developers are constantly making updates and improvements.  To see the latest information refer to their GitHub page. They have recently updated to 0.5x beta which has changed the set-up instructions  (basically they have now require the creation of an config.ini file in the set-up directory).  It's pretty straight forward and they include the text within the readme.   https://github.com/tgorgdotcom/locast2plex/blob/master/README.md
