Reply to Anyone has the S4 Manual (English / PDF)?

I've searched throughout the community , checked my account at NI, searched their whole website and googled on many variations, but I cannot find the S4 (controller and/or software) manual anywhere.

I assume it is not illegal to share a manual? But I cannot find it. Can someone send me (or upload it here?) a PDF manual in English?

I would be very pleased if that's possible

(EDIT: By the way, I don't have the software!! This question is not because I downloaded it illegally, I just want insights on the functionality of the software & controller)
