Sophisticated, lightweight & simple CMS, homepage: Bolt.cm
Bolt is a tool for Content Management, which strives to be as simple and straightforward as possible. It is quick to set up, easy to configure, uses elegant templates, and above all: It's a joy to use. Bolt is created using modern open source libraries, and is best suited to build sites in HTML5 with modern markup.
From a technical perspective: Bolt is written in PHP, and uses either SQLite, MySQL or PostgreSQL as a database. It's built upon the Silex framework together with a number of Symfony components and other libraries. Bolt is released under the open source MIT-license.
Create a new folder, and clone from github. Then use composer to get the Silex micro-framework and components:
git clone git://github.com/bobdenotter/bolt.git bolt
cd bolt
curl -s http://getcomposer.org/installer | php
php composer.phar install
And you're good to go.
More detailed instructions can be found in the Setup section in the documentation.
