+# CE Checkers
+
+This is a short program for the game of checkers on the TI-84+ CE graphing calculator.
+
+[Rules](https://www.thesprucecrafts.com/play-checkers-using-standard-rules-409287)
+
+## Controls
+
+ * Arrow keys move the cursor
+ * `+` adds/removes a space from the current move
+ * `-` clears the current move
+ * `Enter` plays the move
+
+In order to make a move, use `+` to select the piece and each of the squares it should move to in order, then press `Enter`.
+
+## Building from source
+
+This program requires the [CEdev C toolchain](https://github.com/CE-Programming/toolchain) to build. Once that is installed properly, the program can be built with the `make` command.
+
+## Debugging
+
+This program can be built with some debug features that use [CEmu](https://ce-programming.github.io/CEmu/)'s console. In order to build the program in debug mode, edit the `makefile` and uncomment this line:
+
+```Makefile
+.DEFAULT_GOAL := debug
+```
+
+### Debugging commands
+
+ * `×` prints the current move to the console
+ * `÷` prints out all possible moves for the current player
+
+Moves are printed using indexes starting from the first black square (0) and going from left to right, then up and down, to the last black square (31). `-1` indicates no move.
