The minimal requirements for this book would be a web server with PHP 5.2 (5.2.18 or later preferred) and a database server (MySQL version 4.1 or later, or PostgreSQL). Any web server should work, but one recipe uses Apache's
mod_rewrite, so to test that one, an Apache-compatible web server would be needed. We will also need a modern web browser (IE 8+, Firefox 3.x+, Safari, or Chrome), some kind of text editor, and, of course, CMS Made Simple version 1.9.x.
CMS Made Simple's full requirements can be found at http://wiki.cmsmadesimple.org/index.php/User_Handbook/Installation/Requirements and the code can be downloaded at http://dev.cmsmadesimple.org/project/files/6.
