Tutorial for making a Typst package?

Hello, sorry if I missed something. Is there an official tutorial for Typst packages? I think I didn’t see one in the documentation, and there are only community-made ones, but I’d like an official one if there is, or some recommendations if there isn’t. I’m still learning it.

All typst pkgs are at:

On its main page:

If you want to submit your own package, you can follow our documentation on publishing packages that will guide you through the process and give you some tips.

So… I read through all the information and I’ll know how to write a package? I just need to wire the entrypoint and it’ll behave just like importing the wired file?
