Renaming the Top-Level Entry File
When you generate output for your project, a top-level entry file is created. This file defines the frameset for the help and gives the user a file to open that displays the complete help. By default, the top-level entry file is named index.html, but you can specify any name you need for the top-level entry file as long as you specify an .html or .htm extension.
To rename the top-level file
On the Project menu, select the Active Target you want to specify settings for.
On the Target menu, click Target Settings.
In Top level filename, type the name you want to use for the top-level entry file.
Regenerate the project and review the results.
