I have taken over the website management for the person that created the website an can not figure out how to edit the structure of the website.
Please find time to take a look at this tutorial (first couple of parts). http://docs.couchcms.com/tutorials/portfolio-site.html
It will explain the structure of CouchCMS and will be a good introduction to what's going on as general approach.

When you have anything to ask, keep posting in this thread and we'll point to the right direction or help with code.
