How do I create Anchor points between sections of the book?

Hi! I am publishing to kindle - non fiction. As such I want to create anchor points within the book so that readers can quickly jump from one part of the book to another & back using the click of a link. For example โ€œThere are clear statistics to prove this (click here to read the numbers)โ€

Can anyone point me in the right direction please? I know this is possible to do, somehow!!! :wink:

Thanks in advance :slight_smile:
