+Development is divided into phases.
+The project will eventually be open sourced. However, I will work on the first few phases myself, to maximize learning.
+The following is a list of features I'll be planning to add to it:
 
 ## Phase 1 (Basic Features)
+
 - [x] A simple fixed size canvas to draw on using a black coloured stroke.
 - [x] Different shapes like rectangle, ellipse, arrow, line and stroke.
 - [x] An eraser to erase the strokes (deleting the strokes).
 - [x] Testing.
 
 ## Phase 2
+
 - [x] Refactor to try to adhere to SOLID principles and utilize useful design patterns
 - [x] A custom Qt layout for toolbar and properties bar
 - [x] Make canvas infinite and add ability to move the viewport
 - [x] Use an LRU cache based uniform grid to optimize moving the canvas around (now 100% faster!!)
 - [x] A properties bar to change the following properties:
     - [x] Colour of strokes
-    - [x] Stroke width  
-  
+    - [x] Stroke width
+
 ## Phase 3
+
 - [x] Buttons to zoom in/out
 - [x] Pressure senstivity for drawing tablets
 - [x] Selection tool to select items and do these actions:
