# Introduction

Each chapter is comprised of different kinds of content - called blocks. These blocks can be reordered and stacked to form the structure of the chapter. 

To access them, you'll have to be in the node editor view. This is what you see when editing a node.

The node editor is where you'll spend most of your time, because it's in this editor that you'll input all the text and configurations of the nodes. Below is a screenshot of the editor with the correspondent legend.
