Practical guide to create Concrete5 themes This book is great for theme developers new to concrete5 who are looking to use their experience in HTML and CSS to create high quality themes for concrete5. It's assumed that you have worked with HTML before and can also read code as you'll see some basic PHP and JavaScript code. There are a few words about using concrete5, but you're expected to spend a bit of time on your own to get familiar with the concrete5 interface by yourself and by reading some of the articles listed in the book. Readers are expected to have the ability to set up their own concrete5 site, but basic information about the installation and links to follow up are provided though.
