Hugo and PHP

Following this topic and it works great for the index page in CONTENT. My question what if I want to include other subfolders files in CONTENT?

Example:

site
|__content
     |__index (works great at this level)
     |__folder
          |__login(what are the steps for down stream files?)

I have not been successful in figuring this out.

Summary:

Your steps render to the static site for home[index]. How would I generate all other HTML files to PHP in my static site?

Cheers mate
