If you own a mac I advise you to spend your euros for this book because a large part is devoted to a virtual store, which is very interesting, but if you have a Mac you can forget it, it will not work, the installation and commissioning prestashop service on your mac is not possible, and three-quarters of the book will serve you no good, there is no place to ask for help, no nothing forums, so you are alone with your problem, it's a shame because otherwise it would be a very good book with clear explanations for windows users is perfect.
