-There are three different types of spreadsheets inside LON-CAPA.
+There are three nested levels of spreadsheets inside LON-CAPA: a Course Spreadsheet, \index{course level spreadsheet} a Student Spreadsheet, and various Assessment Spreadsheets. The Course spreadsheet provides an overview of student performance and links to each student's details.
+The Student Spreadsheet configures how the overall course grade is to be calculated. Each graded item can
+be configured using an Assessment Spreadsheet to specify how the problem parameters are to be evaluated.
