Where is IOS 11 complete user guide PDF?

Hi,

I can’t find a pdf of the COMPLETE Ipad IOS 11 user guide. All I can find are links to a 9-page summary of what is new In 11. I can find the manual on the apple.com website ( https://help.apple.com/ipad/11/#/iPad8d9d296d) but when I send it to PDF in iBooks, I get the 9page thing again. Based on my cc of the IOS10 user guide, it will exceed 500 pages. Or do I have to PAY for the manual this time???

thanks VERY much! EE
