How to download Iphone User Guide as a PDF file to read offline on a Windows laptop

I just bought my first Apple product, an iPhone 14. I am a long time Windows and Android user just beginning the journey of learning the Apple ecosystem. The 64 mm by 66 mm instruction booklet that came in the box with the iPhone 14 tells me to review the "iPhone User Guide" at support.apple.com/guide/iphone. The instructions also say that I can download the guide from Apple Books, but provides no information about HOW to download the guide. I want to download the guide as a pdf file to read offline on my Windows laptop. I have not been able to figure out how to do this. Can somebody please provide guidance on how to do this?
