To use a lesson, you have to fill in some basic lesson information, which includes:
Title
Duration
Country
School
Subject
Group/Level
Lesson information helps label the lesson material, making it easier to find in the search environment.
In the editing screen, you can find the lesson information under 'Options' followed by 'Settings.'
Lesson information can always be modified and added via the cogwheel icon in the upper right corner of the editing screen.
