I have restructured the book into different sections. Now, when you look at the left side navigation bar, you will see the various sections, each accompanied by an arrow. When you click on the arrow, it opens a drop-down menu. However, instead of just having a drop-down, each link should provide a brief explanation of what that section focuses on. For example, the link for "Workflow" should describe how it relates to the overall big life cycle.
