 #Convex Hull Visualizer
 
-This application is currently under development. The purpose of the program is to visualize computational geometry algorithms (ex: Graham Scan) to generate convex hulls for a series of points inputted by the user.
+This Android app is currently under development. The purpose of the program is to visualize computational geometry algorithms (ex: Graham Scan) to generate convex hulls for a series of points inputted by the user.
 
-##Progress
-* Added grid implementation
-* Functioning Graham Scan algorithm in O(NlogN) time
+##Features
+* Allows user to plot points on a canvas
+* Permits user to customize canvas using multi-touch gestures and through settings screen
+* Features color customization and edge/node size
+* Generates convex hull using Graham Scan algorithm in O(NlogN) time
 
 ##Further Development
-* Include multi-touch gestures to zoom in/out
 * Include Grift-Wrapping Algorithm O(N*H)
-* Include settings to change graphic settings
-* Add nice icon
+* Include nice animations
+* Add nice icon
+
