Our team has been working steadily at producing the Drupal 8 Media Guide, which provided a thorough set of documentation relating to Media in D8.
We also hope that this guide will help you understand best practices and get started using media in your Drupal 8 project today. We also welcome any feedback that you may have.
We're continually working to improve the Guide, and over time we'll be adding examples of how these modules can be integrated. Please check out our GitHub page to get involved
