About this New Edition

Based on customer feedback from the acclaimed first edition "Building Websites with OpenCms", this book concentrates on the process of setting up an OpenCms 6 website, with particular attention to the new features of OpenCms 6. The 120 pages in the previous OpenCms title from Packt that covered set up and administration issues have been updated for Version 6, with over 80 new pages added on new features and broader coverage of OpenCms 6 from a non-developer point of view. If you own the previous edition, and are primarily an administrator or manager of OpenCms websites, then we recommend you buy this edition. If you are primarily a developer then you may want to consider our forthcoming title specifically on OpenCms v6 Development. For information on upgrade offers for exisiting buyers please Contact us
