+
+## Quick Setup
+
+This package provides LangChain integration for the LaunchDarkly AI SDK. The simplest way to use it is with the LaunchDarkly AI SDK's `initChat` method:
+
+1. Install the required packages:
+
+```shell
+npm install @launchdarkly/server-sdk-ai @launchdarkly/server-sdk-ai-langchain --save
+# or
+yarn add @launchdarkly/server-sdk-ai @launchdarkly/server-sdk-ai-langchain
+```
+
+2. Create a chat session and use it:
+
+```typescript
+import { init } from '@launchdarkly/node-server-sdk';
+import { initAi } from '@launchdarkly/server-sdk-ai';
+
+// Initialize LaunchDarkly client
+const ldClient = init(sdkKey);
+const aiClient = initAi(ldClient);
+
+// Create a chat session
+const defaultConfig = { 
+  enabled: true, 
+  model: { name: 'gpt-4' },
+  provider: { name: 'openai' }
+};
+const chat = await aiClient.initChat('my-chat-config', context, defaultConfig);
+
+if (chat) {
+  const response = await chat.invoke('What is the capital of France?');
+  console.log(response.message.content);
+}
+```
+
+For more information about using the LaunchDarkly AI SDK, see the [LaunchDarkly AI SDK documentation](https://github.com/launchdarkly/js-core/tree/main/packages/sdk/server-ai/README.md).
+
+## Advanced Usage
+
+For more control, you can use the LangChain provider package directly with LaunchDarkly configurations:
+
+```typescript
+import { LangChainProvider } from '@launchdarkly/server-sdk-ai-langchain';
+import { HumanMessage } from '@langchain/core/messages';
+
+// Create a LangChain model from LaunchDarkly configuration
+const llm = await LangChainProvider.createLangChainModel(aiConfig);
+
+// Convert LaunchDarkly messages to LangChain format and add user message
+const configMessages = aiConfig.messages || [];
+const userMessage = new HumanMessage('What is the capital of France?');
+const allMessages = [...LangChainProvider.convertMessagesToLangChain(configMessages), userMessage];
+
+// Track the model call with LaunchDarkly tracking
+const response = await aiConfig.tracker.trackMetricsOf(
+  (result) => LangChainProvider.createAIMetrics(result),
+  () => llm.invoke(allMessages)
+);
+
+console.log('AI Response:', response.content);
+```

+## About LaunchDarkly
+
+- LaunchDarkly is a continuous delivery platform that provides feature flags as a service and allows developers to iterate quickly and safely. We allow you to easily flag your features and manage them from the LaunchDarkly dashboard. With LaunchDarkly, you can:
+  - Roll out a new feature to a subset of your users (like a group of users who opt-in to a beta tester group), gathering feedback and bug reports from real-world use cases.
+  - Gradually roll out a feature to an increasing percentage of users, and track the effect that the feature has on key metrics (for instance, how likely is a user to complete a purchase if they have feature A versus feature B?).
+  - Turn off a feature that you realize is causing performance problems in production, without needing to re-deploy, or even restart the application with a changed configuration file.
+  - Grant access to certain features based on user attributes, like payment plan (eg: users on the 'gold' plan get access to more features than users in the 'silver' plan).
+  - Disable parts of your application to facilitate maintenance, without taking everything offline.
+- LaunchDarkly provides feature flag SDKs for a wide variety of languages and technologies. Check out [our documentation](https://docs.launchdarkly.com/sdk) for a complete list.

-3. Evaluate a model configuration:
+## Setting Default AI Configurations
+
+When retrieving AI configurations, you need to provide default values that will be used if the configuration is not available from LaunchDarkly:
+
+### Fully Configured Default
+
+```typescript
+const defaultConfig = {
+  enabled: true,
+  model: { 
+    name: 'gpt-4',
+    parameters: { temperature: 0.7, maxTokens: 1000 }
+  },
+  messages: [
+    { role: 'system', content: 'You are a helpful assistant.' }
+  ]
+};
+```
+
+### Disabled Default
+
+```typescript
+const defaultConfig = {
+  enabled: false
+};
+```
+
+## Retrieving AI Configurations
+
+The `config` method retrieves AI configurations from LaunchDarkly with support for dynamic variables and fallback values:
+
+```typescript
+const aiConfig = await aiClient.config(
+  aiConfigKey,
+  context,
+  defaultConfig,
+  { myVariable: 'My User Defined Variable' } // Variables for template interpolation
+);
+
+// Ensure configuration is enabled
+if (aiConfig.enabled) {
+  const { messages, model, tracker } = aiConfig;
+  // Use with your AI provider
+}
+```
+
+## TrackedChat for Conversational AI
+
+`TrackedChat` provides a high-level interface for conversational AI with automatic conversation management and metrics tracking:
+
+- Automatically configures models based on AI configuration
+- Maintains conversation history across multiple interactions
+- Automatically tracks token usage, latency, and success rates
+- Works with any supported AI provider (see [AI Providers](https://github.com/launchdarkly/js-core#ai-providers) for available packages)
+
+### Using TrackedChat
 
 ```typescript
-const config = await aiClient.config(
-  aiConfigKey!,
+// Use the same defaultConfig from the retrieval section above
+const chat = await aiClient.initChat(
+  'customer-support-chat',
   context,
-  { enabled: false },
-  { myVariable: 'My User Defined Variable' },
+  defaultConfig,
+  { customerName: 'John' }
 );
+
+if (chat) {
+  // Simple conversation flow - metrics are automatically tracked by invoke()
+  const response1 = await chat.invoke('I need help with my order');
+  console.log(response1.message.content);
+
+  const response2 = await chat.invoke("What's the status?");
+  console.log(response2.message.content);
+
+  // Access conversation history
+  const messages = chat.getMessages();
+  console.log(`Conversation has ${messages.length} messages`);
+}
 ```
 
-For an example of how to use the config please refer to the examples folder.
+## Advanced Usage with Providers
+
+For more control, you can use the configuration directly with AI providers. We recommend using [LaunchDarkly AI Provider packages](https://github.com/launchdarkly/js-core#ai-providers) when available:
+
+### Using AI Provider Packages
+
+```typescript
+import { LangChainProvider } from '@launchdarkly/server-sdk-ai-langchain';
+
+const aiConfig = await aiClient.config(aiConfigKey, context, defaultValue);
+
+// Create LangChain model from configuration
+const llm = await LangChainProvider.createLangChainModel(aiConfig);
+
+// Use with tracking
+const response = await aiConfig.tracker.trackMetricsOf(
+  (result) => LangChainProvider.createAIMetrics(result),
+  () => llm.invoke(messages)
+);
+
+console.log('AI Response:', response.content);
+```
+
+### Using Custom Providers
+
+```typescript
+import { LDAIMetrics } from '@launchdarkly/server-sdk-ai';
+
+const aiConfig = await aiClient.config(aiConfigKey, context, defaultValue);
+
+// Define custom metrics mapping for your provider
+const mapCustomProviderMetrics = (response: any): LDAIMetrics => ({
+  success: true,
+  usage: {
+    total: response.usage?.total_tokens || 0,
+    input: response.usage?.prompt_tokens || 0,
+    output: response.usage?.completion_tokens || 0,
+  }
+});
+
+// Use with custom provider and tracking
+const result = await aiConfig.tracker.trackMetricsOf(
+  mapCustomProviderMetrics,
+  () => customProvider.generate({
+    messages: aiConfig.messages || [],
+    model: aiConfig.model?.name || 'custom-model',
+    temperature: aiConfig.model?.parameters?.temperature ?? 0.5,
+  })
+);
+
+console.log('AI Response:', result.content);
+```
