# SDK Setup

> Set up the Nuntly TypeScript SDK. Install the package, initialize with your API key, and start sending emails from Node.js or Bun.

This guide provides an overview of the setup process and requirements for using the Nuntly SDK in your applications. Follow the steps below to get started quickly and efficiently.

## Requirements

* Node.js 18+ and TypeScript installed
* A verified sending domain. See [Add a sending domain](/docs/guides/sending-domains).
* A valid API key. See [Generate your API key](/docs/guides/api-keys).

## Install the SDK

Make sure you’ve installed the Nuntly SDK:

<CodeGroup>
  ```bash pnpm theme={null}
  pnpm add @nuntly/sdk
  ```

  ```bash yarn theme={null}
  yarm add @nuntly/sdk
  ```

  ```bash npm theme={null}
  npm install @nuntly/sdk
  ```

  ```bash bun theme={null}
  bun add @nuntly/sdk
  ```
</CodeGroup>

## Initialize the SDK

To start using the Nuntly SDK, you need to initialize it with your API key. Here's a basic example of how to do this in a TypeScript project:

```typescript theme={null}
import { Nuntly } from '@nuntly/sdk';

const nuntly = new Nuntly({
  apiKey: 'YOUR_API_KEY_HERE',
});
```

Replace `'YOUR_API_KEY_HERE'` with your actual API key from the Nuntly dashboard.

For a better security practice, consider using environment variables to store your API key:

```typescript theme={null}
import { Nuntly } from '@nuntly/sdk';
const nuntly = new Nuntly({
  apiKey: process.env.NUNTLY_API_KEY!,
});
```
