 ## About  
 
 Here you can see in realtime how pathfiding algorithms works. You can also draw walls and move the start and end point.
 
-This include :
+Features : 
 
-* `A*`
-* `Dijkstra` (modified version because here is not a cost graph)
+* draw (left click) & remove (right click) walls
+* live searching
+* draw/remove walls after the search ends
+* move end point and see instantly the path
+
+Pathfiding algorithms used :
 
-Soon :
-* `Prim`
+* `A*`
+* `Dijkstra`
 
 ## How To Run
 
-In order to run this, you'll need to install [Processing](https://processing.org/) first. Open Sketch.pde under Sketch folder and you are done.
