I have a whole bunch of FAQs I want to list on a page on my site. I'd like to have the links at the top of the page, leading to the descriptions farther down.

How do I do this?

do a google search and you should find an explanation on how to do this.

Would such instructions apply to any platform or theme, not just Atahualpa?

You are looking fipor HTML syntax - nothing to do with atahualpa
