Documentation for some of configuration File options need to be more detailed

Some of the options for configuration file specifed at https://doc.qt.io/qtinstallerframework/ifw-globalconfig.html need more details.
Like there is confusion between Logo, InstallerApplicationIcon, InstallerWindowIcon and doubt about the different functionalities of Banner, WaterMark, BackGround.
If this documentation can be revised and if some example stating the use of these options can be added, that would be great.
