Thanks! I think this is a good solution for now. I have one minor refactoring suggestion. We should explain this in the docs, but I can also write a few lines later. Definitely at https://rollupjs.org/guide/en/#thisemitfile and probably also at https://rollupjs.org/guide/en/#file-urls

[TrickyPi]

I updated relevant docs, if some information is incorrect (include English grammar or vocabulary), please feel free to correct it.

[lukastaegert]

Thanks a lot! The examples are very good, I slightly tweaked the wording.

Thanks for your help too!
