No idea how to create a modpack, documentation doesn't cover it

[allanonmage]

Describe the bug

This page https://support.modrinth.com/en/articles/8802351-modrinth-modpack-format-mrpack skips over foundational concepts of your modpack, to the point I can't get started with it, let alone follow it.

Since I can't just download a modpack file from your website, I kept looking and found this page https://support.modrinth.com/en/articles/8802250-modpacks-on-modrinth which says that modpacks can be created via MultiMC, but does not list the steps to do so, nor link to them. Obviously, an internet search was unfruitful, as most of them are nowadays.

I am a dev and a sysadmin, please talk nerdy to me.

Steps to reproduce

1. Read docs.
2. Fail.

Expected behavior

Documentation that explains things, and provides a clear example.

A way to manually download a modpack to compare the documentation to reality and see which wins.

Additional context

Curseforge lets you download their modpacks from the website, and I was able to look at their pack format that way. I don't think it does what I want though. I have not installed their "app" because I think that's a terrible idea.
