+# Pong
+
+This is my first attempt with [gint](https://gitea.planet-casio.com/Lephenixnoir/gint) creating an add-in for fx series casio calculators.
+
+## Controls
+
+Since this is a very simple game, controls are not included within the add-in. The controls are as following:
+
+### player 1 
+4 - move up
+1 - move down 
+5 - serve the ball
+### player 2
+÷ - move up
+- - move down 
+x - serve the ball
+
+No score system has been added, yet the game will be played indefinitely.
+
+## Building
+
+I would recommend using [fxsdk](https://gitea.planet-casio.com/Lephenixnoir/fxsdk) to build this with the following:
+
+`fxsdk build-fx` 
+to build for fx series calculators. This should create the pong.g1a file, which you can then copy to your calculator.
