You've successfully installed Drupal 7 and actually already have a fully-functional core Drupal 7 website for your client's business. In Chapter 2, Creating the Artisan Bakers Collective Website, we'll dive right into the Drupal 7 interface and start adding our client's content and setting up the website, as per our client's requirements.
If you want to see an example of the techniques used in this book as well as a live example of the complete website, you can visit http://variantcube.com/artisanbakers/. This site contains all of the examples developed throughout the course of this book. If you have questions about how to use Drupal, please post them on the forum at http://variantcube.com/artisanbakers/forum, and I will try to answer your questions, as quickly as possible. You can search on Drupal.org, using the site's default search box.
