IM for Zimbra 8.0

Hi guys I will get straight to the point. My company just will be using Zimbra 8.0 but they told me to research on how to integrate an IM. So I am thinking of ejabberd or open fire. Here's the thing I am in Entry Level meaning this is my first job and I would like to get some help on how to use ejabberd or open fire for zimbra 8.0. Is there any tutorials? Documents? or anything that can help me on my project. Thanks in advance and please inform me if this is the right category for my post.



thanks, Robin.
