This module is a tutorial (read the README) that will introduce you to using the Drupal 8 Migrate tools to create Islandora content in 8. Whether you will eventually use CSVs or other sources (such as XML or directly from a 7.x Islandora) this tutorial should be useful as it covers the basics and mechanics of migration.

This module is also a Drupal Feature that, when enabled as a module, will create three example migrations ready for you to use with the Migrate API. Each migration comes from one of the files in the config/install folder.
