An RSS feed is just a big text file full of metadata in the form of tags. It looks a lot like html. There are specific tags that indicate things like artist name, location of media files, etc. All you gotta do is plug in the appropriate data next to the appropriate tag. I urge you to look at the template duhlaurien posted in a previous reply. Also this for more high level explainers and guides:

Thanks. I think I get the XML data layout. I can manually add a published RSS feed within AntennaPod. Is that what most listeners do? Or do they use the indexing services and generally stay within that garden?
