Drupal migrations reference: List of properties per content entity

In a previous article we explained the syntax used to write Drupal migrations. When migrating into content entities, these define several properties that can be included in the `process` section to populate their values. For example, when importing nodes you can specify the title, publication status, creation date, etc. In the case of users, you can set the username, password, timezone, etc. Finding out which properties are available for an entity might require some Drupal development knowledge. To make the process easier, in today’s article we are presenting a reference of properties available in content entities provided by Drupal core and some contributed modules.
