Suppose you want to create a hierarchy to match this simple outline:
Tutorial for New Users Module 1: Getting Started Module 2: Creating Your First Report Module 3: Printing the Report Module 4: Saving Your Work and Quitting Task Reference Starting and Stopping To Start the Program To Quit the Program Creating Reports To Create a Detailed Report To Create a Summary Report Concepts for Advanced Users Using Report Hot Links Sharing Reports within a Workgroup Reference Command Summary Report Attributes Summary
Then the general outline of your help volume would look like this. (The body of each topic and IDs for the topics are not shown.)
<hometopic> Welcome to Report Master <chapter> Tutorial for New Users <s1> Module 1: Getting Started <s1> Module 2: Creating Your First Report <s1> Module 3: Printing the Report <s1> Module 4: Saving Your Work and Quitting <chapter> Task Reference <s1> Starting and Stopping <s2> To Start the Program <s2> To Quit the Program <s1> Creating Reports <s2> To Create a Detailed report <s2> To Create a Summary report <chapter> Concepts for Advanced Users <s1> Using Report Hot Links <s1> Sharing Reports within a Workgroup <chapter> Reference <s1> Command Summary <s1> Report Attributes Summary
Indentation is used here to make it easier to see the structure of the help volume. You do not have to indent your files.
"Accessing Topics" describes assigning IDs to topics
"Creating Hyperlinks" describes how to create hyperlinks
