WordPress is all about Themes.
A WordPress Theme determines the look and feel of your website. It determines the layout, the menu options, the colour – pretty much everything!
You can start out without a theme (you’ll get the default WordPress look) but if you want something more, here is an introduction to themes, where to find them and how to get them on your website. Some are free, some are paid for, we guide you through what they are and how to choose.
This tutorial applies to both simple and advanced WordPress systems. The major difference is that in the simple wordpress.com you will not be able to upload new 'slicker' themes, you just use the ones WordPress provides.

In this we suggest some themes – you need to choose the one that is right for you so do watch the tutorial.
When you have done that if you like you can follow up the two sites we showed you and get your theme from Woothemes here or your Thesis theme from DiyThemes.
