 ## Usage
 
-The usage section delves into how to leverage the `@push.rocks/smartai` package to interact with AI models in an application. This package simplifies the integration and conversation with AI models by providing a standardized interface. The examples below demonstrate the package's capabilities in engaging with AI models for chat operations and potentially handling audio responses using TypeScript and ESM syntax.
+The `@push.rocks/smartai` package is a comprehensive solution for integrating and interacting with various AI models, designed to support operations ranging from chat interactions to audio responses. This documentation will guide you through the process of utilizing `@push.rocks/smartai` in your applications.
 
-### Integrating AI Models
+### Getting Started
 
-#### Importing the Module
+Before you begin, ensure you have installed the package as described in the **Install** section above. Once installed, you can start integrating AI functionalities into your application.
 
-Start by importing `SmartAi` and the AI providers you wish to use from `@push.rocks/smartai`.
+### Initializing SmartAi
+
+The first step is to import and initialize the `SmartAi` class with appropriate options for the AI services you plan to use:
 
 ```typescript
-import { SmartAi, OpenAiProvider, AnthropicProvider } from '@push.rocks/smartai';
-```
+import { SmartAi } from '@push.rocks/smartai';
 
-#### Initializing `SmartAi`
-
-Create an instance of `SmartAi` with the necessary credentials for accessing the AI services.
-
-```typescript
 const smartAi = new SmartAi({
-  openaiToken: 'your-openai-access-token',
-  anthropicToken: 'your-anthropic-access-token'
-});
-```
-
-### Chatting with the AI
-
-#### Creating a Conversation
-
-To begin a conversation, choose the AI provider you'd like to use. For instance, to use OpenAI:
-
-```typescript
-async function createOpenAiConversation() {
-  const conversation = await smartAi.createOpenApiConversation();
-  // Use the conversation for chatting
-}
-```
-
-Similarly, for an Anthropic AI conversation:
-
-```typescript
-async function createAnthropicConversation() {
-  const conversation = await smartAi.createAnthropicConversation();
-  // Use the conversation for chatting
-}
-```
-
-### Streaming Chat with OpenAI
-
-For more advanced scenarios, like a streaming chat with OpenAI, you would interact with the chat stream directly:
-
-```typescript
-// Assuming a conversation has been created and initialized...
-const inputStreamWriter = conversation.getInputStreamWriter();
-const outputStream = conversation.getOutputStream();
-
-// Write a message to the input stream for the AI to process
-await inputStreamWriter.write('Hello, how can I help you today?');
-
-// Listen to the output stream for responses from AI
-const reader = outputStream.getReader();
-reader.read().then(function processText({ done, value }) {
-  if (done) {
-    console.log("No more messages from AI");
-    return;
+  openaiToken: 'your-openai-token',
+  anthropicToken: 'your-anthropic-token',
+  perplexityToken: 'your-perplexity-token',
+  groqToken: 'your-groq-token',
+  ollama: {
+    baseUrl: 'http://localhost:11434',
+    model: 'llama2'
   }
-  console.log("AI says:", value);
-  // Continue reading messages
-  reader.read().then(processText);
+});
+
+await smartAi.start();
+```
+
+### Chat Interactions
+
+#### Synchronous Chat
+
+For simple question-answer interactions:
+
+```typescript
+const response = await smartAi.openaiProvider.chat({
+  systemMessage: 'You are a helpful assistant.',
+  userMessage: 'What is the capital of France?',
+  messageHistory: [] // Previous messages in the conversation
+});
+
+console.log(response.message);
+```
+
+#### Streaming Chat
+
+For real-time, streaming interactions:
+
+```typescript
+const textEncoder = new TextEncoder();
+const textDecoder = new TextDecoder();
+
+// Create input and output streams
+const { writable, readable } = new TransformStream();
+const writer = writable.getWriter();
+
+// Send a message
+const message = {
+  role: 'user',
+  content: 'Tell me a story about a brave knight'
+};
+
+writer.write(textEncoder.encode(JSON.stringify(message) + '\n'));
+
+// Process the response stream
+const stream = await smartAi.openaiProvider.chatStream(readable);
+const reader = stream.getReader();
+
+while (true) {
+  const { done, value } = await reader.read();
+  if (done) break;
+  console.log('AI:', value); // Process each chunk of the response
+}
+```
+
+### Audio Generation
+
+For providers that support audio generation (currently OpenAI):
+
+```typescript
+const audioStream = await smartAi.openaiProvider.audio({
+  message: 'Hello, this is a test of text-to-speech'
+});
+
+// Handle the audio stream (e.g., save to file or play)
+```
+
+### Document Processing
+
+For providers that support document processing (OpenAI, Ollama, and Anthropic):
+
+```typescript
+// Using OpenAI
+const result = await smartAi.openaiProvider.document({
+  systemMessage: 'Classify the document type',
+  userMessage: 'What type of document is this?',
+  messageHistory: [],
+  pdfDocuments: [pdfBuffer] // Uint8Array of PDF content
+});
+
+// Using Ollama with llava
+const analysis = await smartAi.ollamaProvider.document({
+  systemMessage: 'You are a document analysis assistant',
+  userMessage: 'Extract the key information from this document',
+  messageHistory: [],
+  pdfDocuments: [pdfBuffer] // Uint8Array of PDF content
+});
+
+// Using Anthropic with Claude 3
+const anthropicAnalysis = await smartAi.anthropicProvider.document({
+  systemMessage: 'You are a document analysis assistant',
+  userMessage: 'Please analyze this document and extract key information',
+  messageHistory: [],
+  pdfDocuments: [pdfBuffer] // Uint8Array of PDF content
 });
 ```
 
-### Handling Audio Responses
+Both providers will:
+1. Convert PDF documents to images
+2. Process each page using their vision models
+3. Return a comprehensive analysis based on the system message and user query
 
-The package may also support converting text responses from the AI into audio. While specific implementation details depend on the AI provider's capabilities, a generic approach would involve creating a text-to-speech instance and utilizing it:
+### Vision Processing
+
+For providers that support vision tasks (OpenAI, Ollama, and Anthropic):
 
 ```typescript
-// This is a hypothetical function call as the implementation might vary
-const tts = await TTS.createWithOpenAi(smartAi);
+// Using OpenAI's GPT-4 Vision
+const description = await smartAi.openaiProvider.vision({
+  image: imageBuffer, // Buffer containing the image data
+  prompt: 'What do you see in this image?'
+});
 
-// The TTS instance would then be used to convert text to speech
+// Using Ollama's Llava model
+const analysis = await smartAi.ollamaProvider.vision({
+  image: imageBuffer,
+  prompt: 'Analyze this image in detail'
+});
+
+// Using Anthropic's Claude 3
+const anthropicAnalysis = await smartAi.anthropicProvider.vision({
+  image: imageBuffer,
+  prompt: 'Please analyze this image and describe what you see'
+});
 ```
 
-### Extensive Feature Set
+## Error Handling
 
-`@push.rocks/smartai` provides comprehensive support for interacting with various AI models, not limited to text chat. It encompasses audio responses, potentially incorporating AI-powered analyses, and other multi-modal interactions.
-
-Refer to the specific AI providers’ documentation through `@push.rocks/smartai`, such as OpenAI and Anthropic, for detailed guidance on utilizing the full spectrum of capabilities, including the implementation of custom conversation flows, handling streaming data efficiently, and generating audio responses from AI conversations.
-
-### Conclusion
-
-Equipped with `@push.rocks/smartai`, developers can streamline the integration of sophisticated AI interactions into their applications. The package facilitates robust communication with AI models, supporting diverse operations from simple chats to complex audio feedback mechanisms, all within a unified, easy-to-use interface.
-
-Explore the package more to uncover its full potential in creating engaging, AI-enhanced interactions in your applications.
+All providers implement proper error handling. It's recommended to wrap API calls in try-catch blocks:
 
+```typescript
+try {
+  const response = await smartAi.openaiProvider.chat({
+    systemMessage: 'You are a helpful assistant.',
+    userMessage: 'Hello!',
+    messageHistory: []
+  });
+} catch (error) {
+  console.error('AI provider error:', error.message);
+}
+```
