Example 1: You can use the left Contents pane to browse through the topics. When you click a "book" you'll see the topics it contains, and when you click a topic's title it opens in the right pane. Some topics contain links to other, related topics.

 

Example 2: A topic may be in the Contents pane more than once. For example, Red Beans and Rice is under both the Pork book and the Vegetarian book, as this recipe can be made either way.   

 

Example 3: Another way to find what you need is using the left Search pane. As shown in the example below, topics containing the word you searched for are listed in the left pane, and when you click a topic's title it opens in the right pane.
