WordPress – Das umfassende Handbuch

Rheinwerk Verlag

When I was an active web developer, I wrote this book of almost 1,000 pages that was published by Rheinwerk Verlag (formerly Galileo Press). It’s a technical guide to WordPress and was the bestselling book on content management systems at that time. I’ve maintained the book for 6 editions over 5 years, with the last edition having been released in 2017.
