As soon as you open the app, you will see a screen asking you to select either Day or Night mode. You can choose between these two modes because the background color of the screen changes depending on the mode you choose.

This is the easiest way to read the book because it is in a similar format as any other book. To change the background color, tap the "Changez Khan Background" option at the top of the screen.

The best way to get through the chapters of this book is to first tap on the top right of the screen. Then tap on the next chapter. This will enable you to switch from one chapter to the next. You can also do this by tapping the button that says "Chapter". To move the page forward or backward, tap the buttons at the top of the screen.
