Skins, such as the default skin Vector, are distributed separately. Drop them
into this directory and enable as per the skin's installation instructions.

You can find a list of available skins at
<https://www.mediawiki.org/wiki/Category:All_skins>,
and more information about installing and configuring skins at
<https://www.mediawiki.org/wiki/Manual:Skin_configuration>.

If you are a developer, you might want to fetch the skin tree in another
directory and make a symbolic link:

 mediawiki/skins$ ln -s ../../skins-trunk/FooBar

The default skin Vector can be installed by cloning from Git:
    git clone https://git.wikimedia.org/git/mediawiki/skins/Vector.git

Other skins are also available:
    https://gerrit.wikimedia.org/r/#/admin/projects/?filter=mediawiki%252Fskins%252F
    https://git.wikimedia.org/project/mediawiki


Please note that under POSIX systems (Linux...), parent of a symbolic path
refers to the link source, NOT to the target! You should check the env
variable MW_INSTALL_PATH in case the extension is not in the default location.

The following code snippet lets you override the default path:

 $IP = getenv( 'MW_INSTALL_PATH' );
 if( $IP === false ) {
	$IP = __DIR__ . '/../..';
 }
 require_once "$IP/maintenance/Maintenance.php"; // a MediaWiki core file
