Which template files do i need to build Directory into my theme?

I am struggling to build Directory into my theme. What is the structure of the template files?

The template files in the default theme are arranged differently to those in ui-front/general…?

I have tried adding page-listings.php & archive-listings.php to my theme but neither of them get loaded.

Please can you tell me how to integrate this and build my own template files, telling me which ones i need to create (there is no real documentation for this)
