-# Project
+# Graph with Reflection and Rewrite Nodes
 
-This project requires the following Python packages:
+This project provides a minimal directed graph implementation that supports two special node types:
 
-- `langgraph`
-- `langchain-openai`
+- **ReflectionNode** – passes its input unchanged to its output.
+- **RewriteNode** – transforms its input using a user‑supplied function.
 
-Install them using:
+## Installation
 
 ```bash
-pip install -r requirements.txt
+npm install
 ```
 
-Ensure you have a compatible Python version (>=3.8).
+## Usage
+
+```js
+import { Graph, ReflectionNode, RewriteNode } from './src/index.js';
+
+const graph = new Graph();
+
+// Create nodes
+const start = new ReflectionNode('start');
+const rewrite = new RewriteNode('rewrite', (x) => x * 2);
+
+// Add nodes to graph
+graph.addNode(start);
+graph.addNode(rewrite);
+
+// Connect nodes
+graph.addEdge('start', 'rewrite');
+
+// Evaluate graph
+const result = graph.evaluate();
+console.log(result); // { start: undefined, rewrite: 0 } (example)
+```
+
+## Running Tests
+
+A simple test script (`test.js`) can be added to validate functionality. Run:
+
+```bash
+npm test
+```
