I am starting a Drupal 8 website, with five custom Node types. These Node types need a field that can link to an arbitrary number of Nodes of any type. All information that I've found online is pertinent to Drupal 7 only. For instance, the Entity Reference module (included already in Drupal 8, but in D8 does not support Node references), or the References module (not available for D8).
How can I create a field to link to an abitrary number of Nodes in Drupal 8?
