+# ChatGPT Rust Client
+
+A reverse-engineered ChatGPT client written in Rust, deployed on Hugging Face Spaces.
+
+## Features
+
+- ChatGPT API client implementation
+- WebSocket streaming support
+- REST API server
+- Image processing capabilities
+- Docker-based deployment
+
+## Deployment
+
+This Space uses Docker to build and run the Rust application. The multi-stage build process ensures:
+
+1. Proper dependency caching
+2. Permission handling for Hugging Face Spaces
+3. Optimized final image size
+
+## Environment Variables
+
+- `RUST_LOG`: Logging level (default: info)
+- `API_HOST`: Server host (default: 0.0.0.0)
+- `API_PORT`: Server port (default: 7860)
+
+## Usage
+
+The application runs automatically on Space startup and provides an API endpoint at the configured port.
