Drupal 8.x

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.

Which module use for credit card and debit card payment in drupal 8

Hi, 

my webform works fine on localhost, but online when I try to submit submission or see webform results I get following error: 

Submission: 

Hello everyone,

In a form, I want to save the content of a field when leaving this field, without any submit button.
The following works perfectly while the field type is textarea but it doesn't work anymore when I change to text_format type.
Why is that and how can I fix it ?

Thanks for your help,

Actually i already posted this question on drupal discussions part of stackoverflow so i will just copy and paste it in here:

Currently I am configuring two virtual machines in preparation for one project.

I'm supposed to utilize deploy module in order to sync project between two machines. So far i figured out how to deploy nodes and files, now my challenge is to synchronize user accounts and taxonomies. Is it possible with deploy module?

Hey there,

I've got to say, I'm loving the new Media entities in D8.5 and all the work that has gone into bringing Media to core, this really takes Drupal to the next level of open CMS platforms.

One question/concern I had was, why are there no permissions settings surrounding anonymous viewing of media entities by directly navigating to /media/ pages?
