Catagories page question

Hi all. There seems to be a distinct lack of info regarding Catagory and Product templates and I’m struggling a little…
Is a Catagory Template an actual page, or do I have to "create a page based on my Catagory Template? I have created a Catagories Template and fully designed its layout but cannot create a link to it in the nav links. Any help appreciated…
