 Forest Fire simulates a forest fire over a rectangular array of trees, starting at a single random location.
 
+Usage of the application: `fire forest_size seed`  
+  `forest_size` number of trees in x-direction and y-direction  
+  `seed`        for random fire ignition
+
+Please note that changing the seed will cause a different fire area and significantly affect the time to solution.
+
+## Use cases:
+Small:
+`100 1`
+
+Medium:
+`1000 1`
+
+Large:
+`6000 1`
+
+It is recommended to redirect the standard output of the application to an output file for Medium and larger use cases, e.g.:   
+`./fire 1000 1 > 1000_1.txt`
