The document describes code for implementing the server-side functionality of a WhatsApp clone. It includes classes for representing users, messages, and server connections. The Server class initializes user and message data from files, handles login/signup, and establishes a websocket connection for real-time messaging. It can send and receive messages when connected, or queue messages when offline.
