We've now got a working theme for Open Source Online Magazine. Great Job!

It's probably clear that you can take advantage of all sorts of custom WordPress template hierarchy pages and template tags to endlessly continue to tweak your theme, in order to display custom information and layouts for all types of different scenarios.

How much customization your theme requires depends entirely on what you want to use it for. If you know exactly how it's going to be used and you'll be the administrator controlling it, you can save time by covering the most obvious page displays the site will need to get it rolling, and occasionally create new template files should the need arise. If you intend to release the theme to the public, the more customized page views you cover, the better. You never know how someone will want to apply your theme to their site.

You've now learnt how to set up your development environment and an HTML editor for a smooth workflow. You also have a theme design that uses semantic, SEO-friendly HTML5 and CSS3 with fallbacks for IE7 and 8, which has been broken down into WordPress template pages for flexibility in your layouts. Believe it or not, we're not quite done!

In the next chapter, we'll continue working with our new theme and add additional features to it, such as widget areas and an improved menu, as well as learning ways to allow users to tweak the theme without delving into code. Let's get started!
