Totally agree here. The current target is people who are familiar with the process, and we plan to write more documentation as we start thinking more about accessibility to a broader audience. We actually ran into this issue ourselves while building the tool - the Debian documentation is all there, but not the easiest to approach. These docs are one of the rough edges (sorry!) since we wanted to get this out earlier for feedback.

To answer your direct question: on self-hosted repositories, the URI right now is just a string identifier. We are working right now on a cloud hosted service, and there the URI will help us figure out which repository to actually serve.
