Seems to me that more difficult than figuring out how to assemble the clutch itself, is getting the motor partially disassembled, the stock clutch out, and the new one installed, then properly re-assembled so it doesn't explode when you hit the starter button, or worse, when you're hauling ass down the road or on the track. Wet clutch is quite a bit more complicated and involved than dry clutch. Lots of little parts that have to go on in specific directions and in a specific order, etc.
Looks easy enough to figure out the clutch itself just from the pictures. Worse comes to worst, use bablefish or some other on-line translator to try to get an idea of what it says.
Do you have the service/ shop manual for your bike that explains how to get to the clutch and get it out, then put it back together? Do you have all the correct tools? Have you done that kind of work before?
I have a wet clutch bike with a slipper, the service manual calls for replacing the big nut that holds it on every time you take it off (190Nm torque spec, so it gets worn each time it's installed/ removed and has to be replaced). Your bike may be the same, so it would behoove you to check the manual and order any parts that you'll need to complete the install, like gaskets, o-rings, etc. Sometimes they take a while to get here from Borgo Panigale.
I'm not trying to discourage, just be sure you know what you're doing before you start fiddling with your motor. If you're not confident or don't want to invest the $$$$ in whatever specialty tools you'll probably need to do the job, I'd take it to a good ducati shop and have them do it. Both Spectrum and Pro Italia have race teams and are comfortable with performance parts installation and tuning. Probably 2 or 3 hours labor at $90/hour, plus gaskets, oil, filter, etc. DON"T go to a generic place like Bert's Megamall, DelAmo, etc. They'll f-it up for sure.
Good luck!
