To start with, you should already be familiar with the most current, stable version of WordPress. You should understand the basics of getting WordPress installed and running on a web server or locally on your machine (especially as you'll need an installation to tinker with the examples in this book). Not to worry, I'll point you in the right direction for getting a basic local installation of WordPress on your Mac or PC. Plus, many hosting providers offer easy one-click installs. You'll have to check with your hosting provider to see if they offer WordPress. I'll also point you toward a few other good resources for WordPress installations. Getting WordPress up and running is often the easiest part of using WordPress.
Going a tad more in-depth, you'll do well to know your way around the WordPress administration panel. You'll need to be familiar with adding content to the WordPress publishing system and how posts, categories, static pages, and sub-pages work. You'll also want to understand using the Media upload tools to add images to posts and pages, as well as creating galleries. Lastly, understanding the basics of installing and using different themes and plugins will also be helpful, though we will cover this to some extent in this title.
Even if you'll be working with a more technical WordPress administrator, you should have an overview of what the WordPress site that you're developing for entails, and what (if any) themes or additional plugins or widgets will be needed for the project. If your site does require a specific theme or additional plugins and widgets, you'll want to have those installs handy and/or already installed in your WordPress development installation (or sandbox—a place to test and play without messing up a live site).
What version of WordPress does this book use?
This book focuses on the new features introduced in versions 2.8, 2.9, and 3.0 RC (Release Candidate—as of the writing of this book). Everything covered in this book has been tested and checked in WordPress 2.9.2 and 3.0 RC. While this title's case studies are developed using version 2.9.2 and 3.0 RC, any newer version of WordPress should have the same core capabilities, enabling you to enhance themes and plugins with jQuery for it using these techniques. Bug fixes and new features for each new version of WordPress are documented at http://WordPress.org.
If you are completely new to WordPress, then I recommend you read WordPress 2.7 Complete by April Hodge Silver and Hasin Hayder.
