Here’s an example:

Correct.

No files are expected to be included.  You only include files that you
want to offer.  There is no prescribed file layout, nor is there any
naming convention.

You #:use-module these modules like any other module.

If the repository contains a file “foo.scm” which starts with
“(define-module (foo) …)”, then you can “#:use-module (foo)” after the
repository has been added as a channel.

I suggest putting modules in separate namespaces.  All modules provided
by “guix-bimsb”, for example, are in the “bimsb” namespace.
