I’ve been trying to get some information/instructions on using a core module, the book module in particular (https://www.drupal.org/docs/8/core/modules/book) and I’m not seeing any of what I would consider the body content in the page display. It seems to be virtually the same for all the core module documentation. I’m pretty sure I was able to view the information earlier in the week. I’ve tried both Firefox and Chrome and both display pretty much the same page. Am I looking in the wrong place for detailed documentation? Thank you, in advance, for your assistance.
