Once you have selected your template you should associate the list with the relevant course. Note that even if you don't use Blackboard for your module there will be a course for it within Leganto.
Select the Associate List button. Start to type the name of the module/course and from the drop-down list select the correct one and click confirm.

You can now start to add content to your list.
To ensure it is visible to students you will need to Publish the list.
The Publish button, located on the top right, allows the materials and list to become discoverable. You can check list status in the top left corner under the module title. Examples shows item still in Draft mode.
