 ## Overview
 
-Claude Code Viewer parses JSONL conversation files stored in `~/.claude/projects/` and presents them in a human-readable web UI. Browse projects, sessions, and detailed conversation history with support for tool usage, subtasks, and real-time file monitoring.
+Claude Code Viewer has evolved from a simple conversation viewer into a comprehensive web-based Claude Code client. It provides all essential Claude Code functionality through an intuitive web interface, including creating new sessions, resuming conversations, real-time task management, and live synchronization with your local Claude Code projects.
 
-![](./docs/assets/basic.png)
+The application leverages Server-Sent Events (SSE) for real-time bidirectional communication, automatically syncing with JSONL conversation files in `~/.claude/projects/` and providing instant updates as conversations progress.
