Introduction

WordPress believes in keeping it a simple/easy to use CMS or Content Management System, and a lot of thought goes into including new functionality as a part of the "core" WordPress code, in order to keep WordPress fast and lightweight. Still, users often find the need to graft additional functionality onto WordPress to meet their needs. This section of the Codex offers guidelines and references for anyone wishing to modify, extend, or contribute to WordPress.
