For the non techies following along, when we talk about an RSS feed, this is literally the raw dog file you get. If you look closely you'll see theres a lot of lines that might look similar in structure to this:

Its basically defining various fields - this one in particular defines who is the recipient of the zaps, the name of the recipient, their node address, their % split, etc.
Just like building a website you can either raw dog edit the html (the rss feed) or utilize a service like godaddy that has a visual builder (like podhome.fm ) that you fill out a regular web form and submit for them to build the feed for you.
