-The goal of this project is to build a clean, fast chess engine in C that starts from a FEN string and produces fully legal moves, verified via PERFT for correctness and speed. It uses a bitboard architecture with precomputed attack caches (pawns, knights, king; sliders later) and a small, well-structured codebase that’s easy to extend. The emphasis is on correctness-first approach (FEN → board → legal movegen → perft). Later, we will incorporate different algorithms and methods of evaluating chess positions to enable an AI player.
+# Chess Engine in C — Project Goal
+
+Build a clean, fast chess engine in C that starts from a FEN string and produces fully legal moves, verified via **PERFT** for correctness and speed.
+
+## Approach
+- **Correctness-first engine:** `FEN → board → legal movegen → PERFT`
+
+## Future Work
+- Incorporate algorithms and evaluation methods for chess positions to enable an **AI player**.
+
+- Build an API to facilitate chess games with the AI player over the web.
+  - Starting with a commandline client.
+  - Later building a web based client.
