+
+This module allows you to order several courses at once. This generates
+an invitation link through which other users can request to participate
+in the course without having to be registered users. The number of
+participants is limited to the number of courses ordered.

+
+Configuration
+=============
+
+To enable this functionality on a course:
+
+1. Create or edit a course from the backend.
+2. Set the **Enrollment Policy** to **On Payment**.
+
+This ensures that access to the course is restricted to users who have
+completed a valid purchase.
+
+Usage
+=====
+
+When a user orders a course with a quantity greater than 1, a
+participation link will be sent to the customer by email.
+
+There are two ways to use the participation link:
+
+-  **Registered users** can access the course directly without having to
+   make a new order.
+-  **Anonymous users** will be asked to enter identification details,
+   which will allow them to register and return to the course later.
+
+Access is limited to the number of places acquired. Once all places have
+been used, no additional users will be able to register via the
+participation link.
+

+When a user orders a course with a quantity greater than 1, a
+participation link will be sent to the customer by email.
+
+There are two ways to use the participation link:
+
+- **Registered users** can access the course directly without having to
+  make a new order.
+- **Anonymous users** will be asked to enter identification details,
+  which will allow them to register and return to the course later.
+
+Access is limited to the number of places acquired. Once all places have
+been used, no additional users will be able to register via the
+participation link.
