If you answered yes to all those questions, then this book is for you!
In 5 steps, I will walk you through the process of creating and building an EPUB 3 format e-book, which you can publish on 15+ digital book stores, including Leanpub, Draft2Digital (Apple Books, Barnes & Noble, Kobo, and more), and Amazon KDP.
To save you time, this book includes "Leanbook" a quick-start Sphinx project template as a downloadable zip file.
With Leanbook, you get 3 font themes, live-preview, sample copyright page and a glossary, a book cover template, and more.
If you are new to reStructuredText, you can consult the sample chapters in Leanbook. For a step-by-step approach, you can get my beginner's guide: "reStructuredText for Sphinx".
