 -- CONFIGURATION --
 
+This module has no implicit configuration, it merely gives you another option when you are setting
+up your image settings. When you edit an image style at admin/config/media/image-styles, you will
+be given an option to add interlacing to the images. Here's how to do that:
+
 * Go to admin/config/media/image-styles andedit target style
 * From dropdown list select "Progressive" option
 * Add effect and that's it
