+Geometric Separators and the Parabolic Lift
 ====================
 
-This application is based off the paper [**Geometric Separators and the Parabolic Lift** by Don Sheehy](http://google.com).
-demonstrates usage of a new algorithm for finding a geometric separator for 2-D points.
-
 About:
 ------
 
-The simple Processing program will allow you input a number of 2-D Euclidean points using a mouse and calculate the geometric separator. Tentatively, you will also be able to provide a file of predefined points (e.g. .csv format).
+This Processing application is based off the paper [**Geometric Separators and the Parabolic Lift** by Don Sheehy](http://donsheehy.net/research/sheehy13geometric.pdf) and demonstrates basic usage of an algorithm (in the above paper) for finding a geometric separator for 2-D points.
 
 Usage:
 ------
 
+The application consists of a canvas and two buttons. It will allow you input a number of 2-D Euclidean points using a mouse and calculate the geometric separator. Tentatively, you will also be able to provide a file of predefined points (e.g. .csv format).
+
 Click the mouse anywhere on the canvas to create a new input point. When you have completed your input, either press 'Reset.' to clear it or 'Calculate.' to find the separator.
 
 Features:
 ---------
 
-The program will visualize several components of the algorthm:
+The program will visualize several components of the algorithm:
 
 * Highlights the estimated centerpoint for your input.
 * Shows the separator in relation to your input.
