How to use ckeditor with mediawiki

How do you replace the defualt editor for mediawiki with ckeditor?

I uploaded the ckeditor files to my website and the samlple page works just fine, but the only documentation I can seem to find explains how to setup fckeditor - I'm using the latest version of ckeditor.

Can someone help me out, or point me to the right direction?

Sample page with ckeditor: http://www.xsyonwiki.org/extensions/ckeditor/_samples/

thanks in advance!
