To make registration clear for students you should build a link to the tool in your Course Content Feed. To do so, click "View Course & Institution Tools" in the course's Details and Actions menu.
A sidebar will open showing several available tools. If Turning is visible in the initial list, click the plus sign next to the course tool; if it is not, click "Browse All Course Tools" at the bottom of the sidebar.
This will bring you to a full list of available course tools. Click the Plus sign for Turning Account Registration to add the tool to your course.
The tool will be added in the form of a link in your Course Content feed. This link will be hidden from students by default; you will have to use the dropdown below the link to make it visible before students can use it to register their clickers.
