Scenario
As an admin or site owner, you want to enable your creators to offer self-paced learning content (such as courses, videos, articles, codelabs, assessments, and linked content) to their audiences.
Solution
You can either reach out to Support, or as an Admin, 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 and assessments. 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.
