CKFinder installation in asp.net - distribution files?

I have an ASP.net project and I'm testing CKFinder, but I ran into a problem when installing.
In the instructions step 1 it says:

"Copy the distribution files to your web server and place them in the /ckfinder/"

Which files does it mean by "Distribution files"? Where do they go?

I assume that the folder structure changes from that in the downloadable archive, so that the javascript + xml goes into a Scripts folder and the aspx files goes in another and the target folder would be a completely new folder. I assumed wrongly that it meant the entire contents of the zip simply in it's own folder and I added the whole thing to my project - naturally it crashed hard as there suddenly was two AssemblyInfo.cs files. Thank goodness for version control.

My project is running MVC3 and I think I can figure it out with time but imho the install instructions are lacking. If you don't support ASP.net MVC, that should be stated as well as it is quite popular.
