+# Game of life
+
+This implementation of [John Conway's game of life][1] developed with processing language 
+with python-mode use a random seed and mouse interaction to set seed. At any 
+instant, the user can pause the simulation to change the state of any cell. 
+Can too interact in the execution time.
+
+
+## How to execute the simulation
+
+To run the simulation is needed an installation of [Processing 3.5.4 IDE][2] and 
+add the python-mode from the top-right menu. Once you have the Processing IDE 
+go to the File menu, select the Open option and search for the game_of_life_sketch.pyde 
+file. In the IDE use the run button (top-left corner) to execute the simulation.
+
+If you need to compile this such an application from any operating system 
+(GNU Linux, Mac OS or Windows), go to the File menu and search for the
