The rule of thumb for this book is that you don't need to read what isn't relevant to your task at hand. Whether you have experience with Moodle or are absolutely clueless, it doesn't matter. Browse this book, and you'll find just the right starting point. Isn't that what the For Dummies books are all about? This book is structured modularly, so you don't have to read the Technical Stuff icons. If you work for an organization that has a system administrator looking after Moodle, you don't need to worry about the technical stuff or anything that says Administrating Moodle. If you're an IT guru, you can avoid the sections on how to develop the eLearning course and how to structure great online courses.
