Use Migrate for importing content?

Just leaving a comment for those who don't need to export content, but looking for a way to create nodes and terms, for example for content during development, in which case Drupal core module Migrate offers an alternative solution.

There is a great ressource at https://understanddrupal.com/migrations, and with Migrate module, a custom module with three files is all that is needed to create nodes and terms--not connected in this example, though that is of course possible (code taken from ud_migrations_first and ud_migrations_multivalue_terms):

ud_migrations_first.info.yml
