 ## Description
 
 This is a simple snake game made designed using Ratatui as TUI library and Rust as programming language.
@@ -30,7 +28,7 @@ The project is divided in 3 main modules:
 
 - `game`: Contains the game logic
 - `main`: Contains the TUI rendering logic and the main loop
-- `coord`: contains the `Coord` struct that represents a 2D coordinate
+- `collision_detection`: is an external lib that contains the collision detection logic
