How to link to a self-created site in pinax(0.9a2)?

I have to implemented two links in my navbar! However I want to add a project written by myself to the site! The first step is to link to the site.

How to do that?

I appreciate your answer!!!

UPDATE

I tried it with simply writing the path into the ref link, but I get:

Page not found (404)

my folder is in my template directory:

            <li id="tab_first">
                <a href="functionality/function.html">First Usecase</a>
            </li>

Whats my mistake?

Solution

<a href='/'>This</a>
