+## Overview
+
+Learn to generate a simple invoice and send it as an email attachment using [Resend](https://resend.com).
+
+## Prerequisites
+
+1. [Publish the invoice template](/usage/publishing-to-the-cloud) to the htmldocs.
+
+2. Install the required dependencies:
+
+<CodeGroup>
+```bash npm
+npm install resend
+```
+
+```bash pnpm
+pnpm install resend
+```
+
+```bash yarn
+yarn install resend
+```
+
+```bash bun
+bun install resend
+```
+</CodeGroup>
+
+3. Set up your Resend API key in your environment:
+
+```bash
+RESEND_API_KEY=your_resend_api_key
+```
+
+## Implementation
+
+Here's a complete example showing how to generate an invoice and send it via email:
+
+```typescript
+import { Resend } from 'resend';
+
+const resend = new Resend(process.env.RESEND_API_KEY);
+
+interface BilledTo {
+  name: string;
