+Enrollment Event Types
+=========================
+
+These event types are fired by the server in response to course enrollment
+activities completed by a student.
+
+* ``edx.course.enrollment.activated`` is fired when a student enrolls in a
+ course. On edx.org, this is typically the result of a student clicking
+ **Register** for the course.
+
+* ``edx.course.enrollment.deactivated`` is fired when a student unenrolls from a
+ course. On edx.org, this is typically the result of a student clicking
+ **Unregister** for the course.
+
+In addition, actions by instructors and course staff members also generate
+enrollment events. For the actions that members of the course team complete that
+result in these events, see :ref:`instructor_enrollment`.

+Instructor Enrollment Events
+=============================
+
+In addition to the enrollment events that are generated when students
+enroll in or unenroll from a course, actions by instructors and course staff
+members also generate enrollment events.
+
+* When a course author creates a course, his or her user account is enrolled in
+ the course and the server fires an ``edx.course.enrollment.activated`` event.
+
+* When a user with the Instructor or Course Staff role enrolls in a course, the
+ server fires ``edx.course.enrollment.activated``. The server fires
+ ``edx.course.enrollment.deactivated`` events when these users unenroll from a
+ course.
+
+* When a user with the Instructor or Course Staff role uses the **Batch
+ Enrollment** feature to enroll students or other staff members in a course,
+ the server fires an ``edx.course.enrollment.activated`` event for each
+ enrollment. When this feature is used to unenroll students from a course, the
+ server fires a ``edx.course.enrollment.deactivated`` for each unenrollment.
+
+For details about the enrollment events, see :ref:`enrollment`.
