In your course, click on the Assignments page and then click on the +Assignment button.
Go to the Submission Type drop down menu and choose External Tool.
Paste the LTI link you want to add from the Information Literacy-Core Links page in this guide in the External Tool URL field, then make sure the other assignment settings are configured:
Name: give the assignment a name of your choosing
Display Grade as: Points
Points: Assign a point value. Credo's scoring uses one point per question:
If you assign a different point value, the grade will scale when it is passed back from Credo, e.g. a 4/5 will scale to 8/10 or 80/100. However, if you change the point value after students have taken the quiz, any grades already logged in the grade column will not automatically rescore (this is a function of Canvas' system, not Credo).
Make sure not to assign a point value of 0, which will cause all student scores to display in the grade book as 0.

Check "Do not count towards the final grade" if you do not want the score automatically included in the final grade for the course.
Click "Load this tool in a new tab" if you would like the link to open in a new tab, not embedded within the page.
Click "Save and Publish" if you want to publish the assignment right away, or just "Save" if you will publish it later. The new assignment should display either embedded in the page or as a link to open in a new window, depending on the default configured in the Global Tool Setup step.
