+## FAQ
+
+### What is Prometheus?
+
+Prometheus is a research-backed, production-ready platform that leverages **unified knowledge graphs** and **multi-agent systems** to perform intelligent operations on multilingual codebases. Built on LangGraph state machines, it orchestrates specialized AI agents to automatically classify issues, reproduce bugs, retrieve relevant context, and generate validated patches.
+
+### What are the key capabilities?
+
+| Feature | Description |
+|---------|-------------|
+| **Automated Issue Resolution** | End-to-end bug fixing with reproduction, patch generation, and multi-level validation |
+| **Feature Implementation** | Context-aware feature request analysis, implementation planning, and code generation |
+| **Intelligent Context Retrieval** | Graph-based semantic search over codebase structure, AST, and documentation |
+| **Multi-Agent Orchestration** | Coordinated workflow between classification, reproduction, and resolution agents |
+| **Knowledge Graph Integration** | Neo4j-powered unified representation of code structure and semantics |
+| **Containerized Execution** | Docker-isolated testing and validation environment |
+| **Question Answering** | Natural language queries with tool-augmented LLM agents |
+
+### How does Prometheus compare to other systems?
+
+| System | Core Description | Prometheus Advantage |
+|--------|-----------------|---------------------|
+| **SWE-Agent** | Single LLM-computer interface | ✅ Multi-agent collaborative reasoning across files/commits |
+| **Lingxi** | Multi-agent bug fixing | ✅ Unified Codebase Knowledge Graph + long-term memory (Athena) |
+| **TRAE** | Multi-agent reasoning framework | ✅ Deep reasoning and knowledge unification |
+| **OpenHands** | General-purpose AI developer | ✅ Contextual understanding + code reasoning |
+
+### What achievements has Prometheus made?
+
+- **TOP 5 and TOP 1 🏆** in agents using gpt-5 in the **[swebench leaderboard](https://www.swebench.com/)** for automated software engineering using LLMs
+- Research paper: [arXiv:2507.19942](https://arxiv.org/abs/2507.19942)
+
+### What is the Multi-Agent Architecture?
+
+Prometheus uses specialized agents for different tasks:
+- **Classification Agent** — Categorizes issues (bug/question/feature/doc)
+- **Reproduction Agent** — Reproduces bugs automatically
+- **Resolution Agent** — Generates validated patches
+
+### What tech stack does Prometheus use?
+
+- **LangGraph** — State machine orchestration
+- **Neo4j** — Unified codebase knowledge graph
+- **Docker** — Containerized execution environment
+- **Athena** — Long-term memory system
+
+### How to get started?
+
+1. Clone the repository: `git clone https://github.com/EuniAI/Prometheus.git`
+2. Set up Neo4j database
+3. Configure LLM API keys
+4. Run agents via LangGraph workflows
