Do NOT try to import your students. Let them know (e.g. via Brightspace) that you have created the course in Queue and tell them to enroll themselves in it.
### Adding TAs to Your Course
1. After the course is created, it's `Info` page will be displayed. Alternatively, click on `Queue` in the upper left corner (this will get you to the home page) and select the course you wish to add your TAs to.
