The Dr.Explain tool automates many things in help file authoring process. You may focus purely on the content of your help file or documentation manual. The program will get many boring  operations out of your work.

 

For instance, the Dr.Explain can automatically  create a list of child subtopics in the bottom of each page. Look at the picture below:

 

 

The user don't have to look through the main help menu searching the nested pages of a currently selected topic. The sub topics are listed right on the page and the Dr.Explain will keep this list actual.

 

The Dr.Explain is a professional level help authoring tool that will pay for itself on the first project because it's a great time and money saver.
