Since 2009, a lot of people have tried Sozi and found it useful. Amazing creations have been made with it, and I have received incredible support from all over the world.
Sozi is still a personal project that I develop mostly alone in my spare time. Over the years, while many users, including myself, were expecting new features and bug fixes, writing code has often felt like a better use of my time than writing documentation.
Today, I realize that the documentation for Sozi needs to be updated and reorganized. I usually feel that some questions on the users forum would be easier to answer if there was a real Sozi user guide available. For this reason, I have started a complete rewrite of the documentation in the form of an online book. I have also reserved a specific domain name for this book: http://sozi.guide
Like Sozi, the book will be published under a free license, and at a reasonable price: "pay what you want". I hope you find it useful and entertaining.
