How to create an archive page.

In Atahualpa you can specify, in the theme options, a page ID to display the archive content on.

I am having trouble as to how exactly you would do that same thing in Montezuma. Do you have to code your own archive page template?

If so, I have absolutely so idea how to start on something like that.

Thank you for the help! I am sure this is a dumb question, just not familiar with how this theme works yet.
