Access author YAML field?

How do I access the author YAML field? I tried "page.author" and it doesn't work.

I'm talking in the context of making a blog theme... Loosely following the Blog skeleton...

if you have author set in the page headers, and you are trying to access from a Twig template, it would be:

{{ page.header.author }}

There is an example of this in the Theme Variable Docs.

Ah, ok! Can I create another field there? Like "description"?

You can create any field you like in the page headers, yes.

OK. Thank you!
