+### Reference:
+This game was created taking [gbdev.io's assembly course](https://gbdev.io/gb-asm-tutorial) as a base.
+I used this guide to learn and for the structure of my game. All functions were reimplemented by me tough.
 
 ### How to:
-assemble: `make all` [requires rgbds]
 
-run     : `make run` [requires mgba-qt]
+assemble: `make all`  [requires rgbds]
+run     : `make run`  [requires emulicious]
+cleanup : `make clean`
