I need to create a new skin but I having trouble figuring out to do this and get the skin to be recognised by MediaWiki. I understand that I need to create a new SkinXXX.php file in the include directory and also a new css file in the stylesheet directory. But, how can this new skin be registered in MediaWiki so that I can use it with the wgDefaultUserOptionsEn['skin'] variable in Language.php?

I would greatly appreciate any help.

Thanks in advance,
