how-to yum remove gnome anf yum install kde?

[Gary Kline]

	I found out how to install Fed-17 [[somehow]]; I now have Gnome
	that I do not prefer.  I've install konsole and I have a bunch of
	KDE libraries.  

	Q: what is the best way to remove gnome and install KDE?  Last time
	it messed up my UEFI {?}{bootloader}.  this time I want to be 
	Extremely careful.
