If you want to link to a static page you can create a User Defined Template, thats ProStores speak for a page you created in Design Studio, and use this code for the link.
<ss:link source="$templateSet.templates['*****']">page name</ss:link>

To create a static page go to Design Studio > Click Add a Page Template > type in the page name, which is represented by the ****** in the code above and the rest of the info > Choose User Defined Template from the final drop down box.

You then place the link in the part of the site you want it to show up in.
