On AppStorm.net there's a new tutorial posted showing you how to use the PyroCMS content management system (CodeIgniter-based) to set up a simple and easy content repository.

With a really nifty content-management system called PyroCMS, this needn’t be something to worry about. In this article, I’ll be showing you how to get PyroCMS installed on a LAMP web server and the basics of creating content and working with the highly-extensible system it offers.

They start with an overview of what PyroCMS is and some of the requirements you'll need to get it up and running. They walk you through the installation process including the database, server checks and permissions needs. They also help you customize it a bit for your site and set up some basic sample content.
