Canvas@Illinois , Turnitin Student Basics
This page has a link to Turnitin documentation.
The following contains information on how to use Turnitin as a Student in Canvas: Feedback Studio Student Guides.
Note: The link above references setting up an account to use Turnitin, but our campus instance of Turnitin in Canvas is already established, and you will only need to submit a document to a Turnitin class assignment to use the tool.
