+# Game of Life
+
+A simulation based on Conway's Game of Life.
+Implemented in C++ using SFML Library.
+
+![img](Demo.png)
+
+## Rules
+
+It's an example of Cellular Automata and follows the following rules:
+
+- Any cell with 3 or more neighbors will die (Overpopulation).
+- Any cell with 2 or less neighbors will die (Underpopulation).
+- Any dead cell with 3 neighbors will come alive (Reproduction).
+
+## Download Instructions
+
+Download the run file and run it.
+
+## Controls
+
+Left Mouse Button - Toggle Cells
+P - Pause/Play
+C - Clear
+R - Randomize
+Right Arrow Key - Speed Up
+Left Arrow Key - Slow Down
