 # Stickfosh
 
-> Stockfish, but worse :)
+> [Stockfish](https://stockfishchess.org), but worse :)
+
+## Overview
+
+This project is a **Chess AI** built using the **Model-View-Controller (MVC)
+pattern**. It provides a modular framework for playing chess, allowing both
+**human vs AI** and **AI vs AI** matches. The AI has undergone several
+iterations, improving its decision-making capabilities through enhancements like
+**alpha-beta pruning**, **move ordering**, **iterative deepening**, and
+**transposition tables**.
+
+## Features
+
+- **MVC Architecture**: The project follows the MVC pattern for clean separation of concerns:
+  - **Model**: Handles chess rules, board state, and AI logic.
+  - **View**: GUI and NoOp (console-based) rendering options.
+  - **Controller**: Manages interactions between players and the game.
+- **Multiple AI Versions**: Several AI versions with increasing complexity have been implemented.
+- **AI vs AI Matches**: A dedicated mode to watch different AI versions compete.
+- **Human vs AI Mode**: Play against the AI using a graphical interface.
+- **FEN Support**: Load chess positions using FEN notation.
+- **Performance Testing (Perft)**: Built-in performance testing for move generation.
+
+## AI Iterations
+
+This project has undergone multiple AI improvements, including:
+
+1. **v0 Random AI**: Selects moves randomly.
+1. **v1 Pure Minimax**: Implements basic minimax search.
+1. **v2 Alpha-Beta Pruning**: Optimizes minimax with pruning.
+1. **v3 Move Ordering**: Prioritizes moves to improve search efficiency.
+1. **v4 Search Captures**: Enhances move ordering by focusing on captures.
+1. **v5 Better Endgame**: Introduces heuristics for endgame play.
+1. **v6 Iterative Deepening**: Dynamically adjusts search depth for better performance.
+1. **v7 Transposition Tables**: Caches board states to reduce redundant computations.
+
+## Installation & Usage
+
+### Prerequisites
+
+- C++ Compiler (C++17 or later)
+- `make`
+- SFML (for GUI rendering)
+
+### Build Instructions
+
+1. Clone the repository:
+   ```sh
+   git clone https://github.com/karma-riuk/stickfosh.git
+   cd stickfosh
+   ```
+1. Create a build directory and compile:
+   ```sh
+   make main
+   ```
+1. Run the program:
+   ```sh
+   ./main
+   ```
+
+## Running AI vs AI Matches
+
+To watch two AI versions play against each other, modify `main.cpp` to instantiate the desired AI versions and run:
+
+```sh
+./main
+```

+
+## Future Improvements
+
+- Implement **opening book** for better early-game decisions.
+- Enhance **evaluation function** with more advanced heuristics.
+- Introduce **neural network-based AI** for machine-learning-driven play.
+- Introduce **Monte-Carlo Tree Search** for stochastic driven play.
