+
+A simple Java platformer game.
+
+## Main Entry Point
+The main entry point of the application is `Display.java`.
+
+## Structure
+- `Display.java`: Entry point and window setup.
+- `Platformer.java`: Game engine and logic.
+- `Player.java`: Player character class.
+- `Tile.java`: Platform class.
+- `Moveable.java`: Interface for moveable objects.
+
+## How to Run
+Use the "Start application" workflow or run:
+```bash
+javac Display.java Platformer.java Player.java Tile.java Moveable.java && java Display
+```
