As an admin or site owner, you want to enable your creators to offer self-paced learning content (courses, videos, articles, and codelabs) to their audiences.
Enable the content types you want to make available to your org, following these steps:
Go to Settings > Site > General
Unless they're already there, add content types to the comma-separated list for Supported content types.
This step exposes the added content types in the Catalog and determines the order in which they appear in the Catalog's navigation pane.
Note that there is an additional setting for enabling courses. See How to enable eLearning courses for more. And, to import codelabs from Google Docs, you must first enable the Google Drive integration.
Save your settings.
You can start creating content for the content types you enabled.
