The book will guide you through your first steps in Amethyst. It will teach you the basics: how the architecture of Amethyst works, how to create a new project, and demonstrate some of the most important features of the engine.
Then, or alternatively, you can check out the Amethyst examples to get a deeper understanding of what an Amethyst project looks like. This will also get you accustomed to the Entity Component System architecture if this concept is new to you.
