+## Description
+
+**castling.club** is a federated chess server built on the ActivityPub protocol.  
+It provides an open and decentralized way to play chess online, where games and moves are visible across the Fediverse.
+
+## Overview
+
+Instead of relying on closed platforms, castling.club uses an arbiter actor (“the King”) to validate moves and mediate matches.  
+This ensures fair play, federation with platforms like Mastodon or Friendica, and community visibility of ongoing games.  
+The service runs as a lightweight Node.js app backed by PostgreSQL.
+
+## Features
+
+- **Federated Chess Matches:** Challenge and play with others across the Fediverse.  
+- **Rule Enforcement:** The arbiter validates each move for correctness.  
+- **Open Identities:** Use your existing Fediverse account; no new silo account needed.  
+- **Game Visibility:** Matches and moves can appear in social timelines.  
+- **Lightweight Service:** Built with Node.js and PostgreSQL for efficiency.
