[SOLVED] How do I switch languages. newby!

[eluser]chefnelone[/eluser]
hi.
Just starting my first multilingual site with ci.

I already have the languages folder in: system/language/
But I have no idea how to manage the language switcher using something like:
<ul>
<li><a href="#">French</a></li>
<li><a href="#">Spanish</a></li>
<li><a href="#">Dutch</a></li>
</ul>

looking for a tutorial or thread where I can start with ?
