 =======
 
-This source repository holds the beginning of a CAS (computer algebra 
-system) written in the programming language Racket. 
+Bracket is a computer algebra system (CAS) written in Racket.
 
-The goal is not to write a CAS with the scope of Maxima and Mathematica,
-but rather to make CAS that can handle high school problems including
-symbolic equation solving, differentiation, integration and sums.
+The goal is to write a CAS suitable for all tasks in a
+high school mathematics curriculum. That is, the goal is not 
+to write a CAS with the scope of Maxima and Mathematica.
+
+The most relevant problem types are: symbolic equation solving, 
+differentiation, integration, sums, and, vector calculations.
 
 The GUI will be inspired by NSpire which interface is very accessible
-to high school students (but whose programming language, well, is
+to high school students (but whose programming language is, well, 
 rather poor). Since Racket supports platforms independent GUIs til
 program will be available on Windows, OS X, and, Linux.
