 ABOUT
 ==========
-The "Attendance" module was developed by

 PURPOSE
 ==========
-The attendance module and block are designed to allow instructors of a course keep an attendance log of the students in their courses. The instructor will setup the frequency of his classes (# of days per week & length of course) and the attendance is ready for use. To take attendance, the instructor clicks on the "Update Attendance" button and is presented with a list of all the students in that course, along with 4 options: Present, Absent, Late & Excused, with a Remarks textbox. Instructors can download the attendance for their course in Excel format or text format.
-Only the instructor can update the attendance data. However, a student gets to see his attendance record.
-
-INSTALLATION
-==========
-The attendance module follows standard installation procedure.
+The Attendance module allows teachers to maintain a record of attendance, replacing or supplementing a paper-based attendance register.
+It is primarily used in blended-learning environments where students are required to attend classes, lectures and tutorials and allows
+the teacher to track and optionally provide a grade for the students attendance.
 
-1. Create folder <path to your moodle dir>/mod/attendance.
-2. Extract files from folder inside archive to created folder.
-3. Visit page Home ► Site administration ► Notifications to complete installation.
+Sessions can be configured to allow students to record their own attendance and a range of different reports are available.

+Feature: Teachers and Students can record session attendance
+    In order to record session attendance
+    As a student
+    I need to be able to mark my own attendance to a session
+    And as a teacher
+    I need to be able to mark any students attendance to a session
+    In order to report on session attendance
+    As a teacher
+    I need to be able to export session attendance and run reports
+    In order to contact students with poor attendance
+    As a teacher
+    I need the ability to message a group of students with low attendance
+
+    Background:
+        Given the following "courses" exist:
