+# Research Brief Generator
 
-Повторный экзамен: Исследовательский бриф (план → шаги → сводка)
+This project implements a **LangGraph** based agent that, given a research topic, produces a short research brief. The workflow is:
+
+1. **Outline** – The LLM generates a 4–5 point outline.
+2. **Research** – For each outline point a single Tavily web search is performed and a concise note is produced.
+3. **Synthesize** – All notes are combined into a ½–1 page brief.
+
+The agent uses:
+- **OpenAI** (ChatOpenAI) for LLM calls.
+- **TavilySearch** for real‑time web queries.
+- **LangGraph** for stateful flow control.
+
+## Prerequisites
+
+- Python 3.10+
+- An OpenAI API key (set `OPENAI_API_KEY`).
+- A Tavily API key (set `TAVILY_API_KEY`).
+
+Both keys can be stored in a `.env` file in the project root.
+
+## Installation
+
+```bash
+pip install -r requirements.txt
+```
+
+## Usage
+
+```bash
+python -m src.cli "Explain to a student the difference between tool and resource in MCP."
+```
+
+The script will print the outline, each research step with notes, and the final brief.
