For "parent" node, how do I show list of child nodes related by child field of type "Entity Reference"? CONTEXT:  Let's say I have a one-to-many relationship between parent "companies" and child "contacts".  Each is its own content type.  The contacts content type has a field of type Entity Reference that can be used to associate a child Contact node to a parent Company.  

QUESTION:  How, when I am on the display of an individual Company node, can I see a list of related contacts right beneath the Company node fields?

Essentially this functionality would be like a "related list" in Salesforce.

Surely there is a module or modules that enable this without having to resort to code?

I've seen the Views Field View module.  It looks promising.  The Panels module looks promising but apparently it is not just for use on its own; it just enables other modules.
Thanks in part to @Niall Murphy's response, I was able to find a Drupal Community Doc that got me further along, though I had to do some translation from Drupal-7 terminology to Drupal-8 terminology before I reached a solution/answer. I've updated the Doc accordingly so you can read it for the solution/answer details. 

Note: No additional modules were needed. I was able to do everything with freshly-installed out-of-the-box Drupal 8.0.2 functionality.
