Setting up a new skin in mediawiki

From OrganicDesign Wiki

A Mediawiki skin consists mainly of one file named by the skin name. For example our skin is called BlueSky.

• Copy Monobook.php and rename it BlueSky.php
• Create a directory in the skins directory called bluesky (note case)
• Load up the new BlueSky.php into an editor and do these global replacements (s/foo/bar/g means replace all occurances of foo with bar)
• s/SkinMonoBook/SkinBlueSky/g
• s/MonoBookTemplate/BlueSkyTemplate/g
• On lines 27-28 change

$this->skinname  = 'monobook';
$this->stylename = 'monobook';
$this->template  = 'MonoBookTemplate';

to

$this->skinname  = 'bluesky';
$this->stylename = 'bluesky';
$this->template  = 'BlueSkyTemplate';
