How does it work?
autodotbiography has been designed to take your answers, your photographs and documents and put them into a template that produces a professionally designed book.
Just how it does it is a commercial secret but let me give you an example. One of the early chapters is called "Hello World Here I Come" (unless you have elected to change the title). If you look at the suggested chapter choices there is one that starts, "The world was a very different place when I was born. We had just come through the second World War. We were still being rationed, that meant we had coupons for meat and petrol and other things like clothing..."
The image below shows how that appears in your book.
