 # Agentic Deep Graph Reasoning Knowledge Network
 
+## 🚀 Quick Start
+
+### Prerequisites
+- Docker and Docker Compose
+- OpenAI API key (or Anthropic API key)
+
+### Installation & Running
+
+1. **Clone and run with one command:**
+   ```bash
+   git clone https://github.com/yourusername/KnowledgeGraphExpander.git
+   cd KnowledgeGraphExpander
+   ./run.sh
+   ```
+
+2. **Access the application:**
+   - Knowledge Explorer UI: http://localhost:8000/explorer
+   - API Documentation: http://localhost:8000/api/docs
+
+3. **Configure API keys** through the Settings tab in the Knowledge Explorer UI
+
+4. **Stop the application** when finished:
+   ```bash
+   ./stop.sh
+   ```
+
+For more options:
+```bash
+./run.sh --help
+```

 ## 🌟 Overview
 A self-organizing knowledge graph system that implements Buehler's (2025) agentic deep graph reasoning architecture. The system builds dynamic, evolving knowledge graphs using multi-agent collaborative reasoning, temporal evolution tracking, and advanced self-organization capabilities as described in the original research.
