How do you add a link for the homepage?

I have this:

Code:

<div id="menu">
        <ul>
            <li class="current_page_item"><a href="">Homepage</a></li>
            <li><a href="">Add</a></li>
            <li><a href="">Search</a></li>
            <li><a href="">About</a></li>
            <li class="last"><a href="">Contact</a></li>
        </ul>
    </div>

The href="" is replaced by whatever was my last view call. What I want is for homepage to go back to the main website page. How do I do that? I don't know what to put there other than index to call the /mycontroller/index function. I didn't know if that was "the way" it was done.
