 # OpenAI API Quickstart - Node.js example app
 
-This is an example pet name generator app used in the OpenAI API [quickstart tutorial](https://platform.openai.com/docs/quickstart). It uses the [Next.js](https://nextjs.org/) framework with [React](https://reactjs.org/). Check out the tutorial or follow the instructions below to get set up.
+This is an example chat app intended to get you started with your first OpenAI API project. It uses the [Chat Completions API](https://platform.openai.com/docs/api-reference/chat) to create a simple general purpose chat app with streaming.

+## Basic request
 
+To send your first API request with the [OpenAI Node SDK](https://github.com/openai/openai-node), make sure you have the right [dependencies installed](https://platform.openai.com/docs/quickstart?context=node) and then run the following code:
+
+```python
+import OpenAI from "openai";
+
+const openai = new OpenAI();
+
+async function main() {
+  const completion = await openai.chat.completions.create({
+    messages: [{ role: "system", content: "You are a helpful assistant." }],
+    model: "gpt-3.5-turbo",
+  });
+
+  console.log(completion.choices[0]);
+}
+
+main();
+```
+
+This quickstart app builds on top of the example code above, with streaming and a UI to visualize messages.
