+# LangGenius Node.js SDK
+This is the Node.js SDK for the LangGenius API, which allows you to easily integrate LangGenius into your Node.js applications.
+
+## Install
+```bash
+npm install langgenius-client
+```
+
+## Usage
+After installing the SDK, you can use it in your project like this:
+
+```js
+import { LangGeniusClient, ChatClient, CompletionClient } from 'langgenius-client'
+
+const API_KEY = 'your-api-key-here';
+const APP_ID = 'your-app-id-here';
+const user = `user_${APP_ID}:user_id`:
+
+// Create a completion client
+const completionClient = new CompletionClient(API_KEY)
+// Create a completion message
+completionClient.createCompletionMessage(inputs, query, responseMode, user)
+
+// Create a chat client
+const chatClient = new ChatClient(API_KEY)
+// Create a chat message
+chatClient.createChatMessage(inputs, query, user, responseMode, conversationId)
+// Fetch conversations
+chatClient.getConversations(user)
+// Fetch conversation messages
+chatClient.getConversationMessages(conversationId, user)
+// Rename conversation
+chatClient.renameConversation(conversationId, name, user)
+
+
+const langGeniusClient = new LangGeniusClient(API_KEY)
+// Fetch application parameters
+langGeniusClient.getApplicationParameters(user)
+// Provide feedback for a message
+langGeniusClient.messageFeedback(messageId, rating, user)
+
+```
+
+Replace 'your-api-key-here' with your actual LangGenius API key.Replace 'your-app-id-here' with your actual LangGenius APP ID.
