+# LangChain Chat Example
+
+This example demonstrates how to use the LaunchDarkly AI SDK with LangChain for chat interactions.
+
+## Prerequisites
+
+1. A LaunchDarkly account and SDK key
+2. An OpenAI API key (for the LangChain integration)
+3. Node.js 16 or later
+
+## Setup
+
+1. Install dependencies:
+   ```bash
+   yarn install
+   ```
+
+2. Set up environment variables:
+   ```bash
+   cp .env.example .env
+   ```
+   
+   Edit `.env` and add your keys:
+   ```
+   LAUNCHDARKLY_SDK_KEY=your-sdk-key-here
+   OPENAI_API_KEY=your-openai-api-key-here
+   LAUNCHDARKLY_AI_CONFIG_KEY=sample-ai-chat-config
+   ```
+
+3. Create an AI Config in LaunchDarkly with the key `sample-ai-config`:
+   ```json
+   {
+     "_ldMeta": {
+       "variationKey": "1234",
+       "enabled": true,
+       "version": 1
+     },
+     "messages": [
+       {
+         "content": "You are a helpful assistant for {{customerName}}. You should be friendly and informative.",
+         "role": "system"
+       }
+     ],
+     "model": {
+       "name": "gpt-3.5-turbo",
+       "parameters": {
+         "temperature": 0.7,
+         "maxTokens": 1000
+       }
+     },
+     "provider": {
+       "name": "langchain"
+     }
+   }
+   ```
+
+## Running the Example
+
+```bash
+yarn start
+```
+
+This will:
+1. Initialize the LaunchDarkly client
+2. Create a chat configuration using the AI Config
+3. Send a message to the AI and display the response
+4. Continue the conversation with a follow-up question
+5. Automatically track interaction metrics (duration, tokens, success/error)
+
+## Features Demonstrated
+
+- **AI Config Integration**: Using LaunchDarkly to configure AI models and prompts
+- **Variable Interpolation**: Using Mustache templates with runtime variables
+- **Chat Conversations**: Multi-turn conversations with message history
+- **Provider Integration**: Using LangChain as the AI provider
+- **Metrics Tracking**: Automatic tracking of token usage and performance
