Modularity tooling intro?

Hi everyone,

I have a bunch of packages in a local repo built for various versions
of Fedora and CentOS, and am looking to build some of them for EL-8.
Clearly the way to go for an EL-8 add-on repo is to build modules, so
that it what I'd like to do. However, I want to do it on my own
infrastructure and hence use the lower-level tooling such as
mbs-manager/mock and local git repos rather than fedpkg/koji/dist-git.

There's quite a bit of documentation around about building modules but
what I've found seems to be either out of date (e.g. uses "mbs-build",
which no longer exists) or is based on fedpkg, which abstracts away the
lower-level operation and is geared towards Fedora infrastructure.

Is there some documentation somewhere that covers getting started with
the tools like mbs-manager?

I thought this workshop looked like a good starting point:

When I discovered that "mbs-build" no longer exists, I tried using
"mbs-manager" but clearly I'm missing something:

$ mbs-manager build_module_locally --file test-module.yaml -s platform:f30

Any pointers anyone?

Maybe this is the document.

In my understanding below command executes "mbs-manager" internally.
I do not run "mbs-manager" command directly.

$ fedpkg module-build
