		This course will cover the fundamentals of Frappe Learning, including how to create and manage courses, enroll students, and track progress.

		You will learn about the following key features of the app:

	   <h3>Key Features</h3>

		1. Structured Learning
		Design a course with a 3-level hierarchy, where your courses have chapters and you can group your lessons within these chapters. This ensures that the context of each lesson is clearly defined by its chapter.

		2. Live Classes
		Group learners into batches based on courses and duration. You can then create Zoom live classes for these batches directly from the app. Learners can view all the live classes they need to attend as part of their batch.

		3. Quizzes and Assignments
		Create quizzes with single-choice, multiple-choice, or open-ended questions. Instructors can also add assignments that learners can submit as PDFs or documents.

		4. Getting Certified
		Once a learner completes the course or batch, you can grant them a certificate. The app provides an inbuilt certificate template that you can use as-is or customize by creating your own template.

	To know more about the app and its features, check out the documentation: https://docs.frappe.io/learning
