Extension talk:Header Footer/Archive

How do you use this extension? What would an example look like?

Problem: Header/Footer not showing: I've installed the extension using PEAR, along with StubManager. Everything seemed fine.

I accessed the page "www.mydomain.com/wiki/index.php/MediaWiki:Hf-nsheader-Main" and added some "test test" message in there by editing the page. However, nothing shows. Isn't this supposed to show the "test test" message in all pages in the Main namespace in my wiki?
