Manual (or handbook) to/for/of <product>?

Question

If I want to advertise a technical product's manual:

<Product> v1.2 Documentation

Official manual for <product> - the fastest, greatest <thing>

is for the right preposition?

to seems simply wrong, but could be used in a claim like:

The easy way to <product>

(long version: "The easy way to learn how to use <product>")

of feels like it's okay, but expresses that the manual is part of <product> (as in possession).

Are there other ways to say this?

for seems like a good choice, because the second half of my sentence refers to <product>, not its handbook, and for doesn't diminish the understandability of this.

Answer 1

While it is not unheard of to use "to" or "of" in similar phrases

A big book of crosswords
The definitive introduction to gardening

(both can be books, texts, or a set of instructions), yet the noun "manual" is more often used with the preposition "for", I think. Google gives >80M results with "manual for", >30M with "manual of", and less than 17M with "manual to" (how much demonstrative those are, is open to debate, of course).
