You can label your courses with topics so that they are easier to find for your students. It's possible to filter on these topics in the course library, so related courses will be easier to find too.
When you go to Studio > Topics, you will see an overview of the topics that are currently on your platform. To create a new one, click 'New topic' in the top right corner. Give your topic a name and click 'Create topic'.
Now when you create a course, you will be able to select the topic you just created.
Finding courses by topic
Go to the course library (Learn > Library). On the right, click the filter icon and select the topic you want to filter on.
Adding a Topic to a course
Click on the course you want to edit in Studio > Courses.
A topic can be added in the right half of the course edit screen.
