1- In your Course Content area, click the + Add content > Content Market
2- Locate Perusall or Perusall deep link, and click on the + to add it the course content area.
3- Refresh the page, and click on Perusall to create a blank course.
By default, when you create an assignment in Perusall, They will automatically make a corresponding grade item for each Perusall assignment in your Blackboard course gradebook that will sync based on your Perusall course settings, so you will not need to make more Perusall links in your Blackboard course. However, if you'd like to make assignment-specific links (called deep links), learn more about Blackboard Integration Features.
