 ## Description
 <!-- Section that clearly presents the project, including its goal and a brief overview -->
 
-cub3D is a graphical project inspired by early 3D games such as *Wolfenstein 3D*.
-Its goal is to render a 3D representation of a maze from a 2D map using the **raycasting technique**, written entirely in C using MLX graphics library.
+**cub3D** is a graphical programming project inspired by the classic game *Wolfenstein 3D*,
+one of the first First-Person Shooters ever created.
 
-This project renders a 3D view of a 2D map described in a '.cub' file.
-The player can move inside the map, rotate the camera and see textures walls, floor and ceiling.
+The goal of this project is to build a **real-time 3D representation of a maze** from a **2D map**, 
+using the **ray-casting technique**, written in **C** and rendered with **MLX42**.
 
-This rendering is possible duo to classic **raycasting algorithm**, where one ray is cast per screen column to calculate wall distance and draw it correctly.
+Each vertical stripe of the screen is rendered by casting a ray from the player’s
+point of view, detecting wall intersections, computing distances, and projecting
+textured walls with correct perspective.  
+Floor and ceiling colors are also rendered to complete the scene.
+
+This project focuses on:
+- Low-level graphics programming
+- Mathematical projection
+- Parsing and validation
+- Real-time rendering performance
+
+
+### Features
+
+- Ray-casting rendering engine
+- Directional wall textures (North, South, East, West)
+- Floor and ceiling RGB colors
+- Player movement and camera rotation
+- Collision detection
+- Strict `.cub` file parsing and validation
+- Clean error handling and memory management
+- MLX42 rendering loop

 ### Requirements
  - Linux or macOS
- - MLX / MLX42
- - 'gcc' or 'clang'
+ - CMake
+ - MLX42 / MLX
+ - C compiler (`gcc` or `clang`)
 
 ### Compilation
+Clone the repository and run:
 ```bash
 make
 ```
+This will:
+- Build MLX42
+- Compile `libft`, `ft_printf`, and `get_next_line`
+- Generate the `cub3d` executable
+
 
 ### Execution
 ```bash
-./cub3D assets/maps/example.cub
+./cub3D assets/maps/map.cub
 ```
 
+The program requires **exactly one argument**: a valid `.cub` map file.
+
 ### Controls
 
-Use W, A, S and D to mover the player.
-Use UP, DOWN, LEFT and RIGHT arrows to rotate camera.
-Use ESC for exit the program.
+| Key | Action |
+|---|---|
+| `W` | Move forward |
+| `S` | Move backward |
+| `A` | Strafe left |
+| `D` | Strafe right |
+| `←` | Rotate camera left |
+| `→` | Rotate camera right |
+| `ESC` | Exit the program |

    - N, S, E or W for the player start position
+- Spaces are allowed and handled correctly 
 
 The map is strictly validated:
-- Exactly one player position
-- Fully closed by walls
+- Exactly **one** player position
+- Map must be **fully closed by walls**
 - Only valid characters
+- No empty lines inside the map
 - RGB values between 0 and 255

+### AI Usage
+
+AI tools were used only as assistance, specifically for:
+- Understanding ray-casting concepts
+- Improving documentation clarity
+- Reviewing logic and edge cases
+
+All generated content was reviewed, understood, and manually implemented.
+No AI-generated code was copied blindly into the project.
