It is very easy for me, I just drag it into my project file then open up Render engine tab; that's all you have do! The rendering quality isn't bad either but sometimes they can get glitchy or make objects look weird (like shadows). Sometimes when running large projects with hundreds of lights this software needs more RAM than what most computers come equipped witn so be prepared if those things happen because some people will say its too slow even tho their PC has plenty o ram left over..but other times not as many problems occur like i said before maybe glitches here an there depending how much memory u give them :].
