Bo is a flavour of the MediaWiki Chameleon skin specially crafted for Amereida and later for Casiopea, which have separate layouts.
Bo is named after the poet Efraín Tomás Bó.
You can install Bo using Composer.
On the root of your MediaWiki installation, run:
COMPOSER=composer.local.json composer require --no-update eadpucv/bo-skin:^2
composer update eadpucv/bo-skin --no-dev -o
This will also install the Chameleon skin and other required packages.
For making it work you need to modify your "LocalSettings.php" as follows:
# - LOAD SKIN
wfLoadSkin( 'chameleon' );
# -- BO SETTINGS
