## Guide

::::steps
:::step{title="Install"}
Get the Resend PHP SDK.

```bash Composer theme={"theme":{"light":"github-light","dark":"vesper"}}
composer require resend/resend-php
```
:::

:::step{title="Send email using HTML"}
The easiest way to send an email is by using the `html` parameter.

```php index.php theme={"theme":{"light":"github-light","dark":"vesper"}}
<?php

require __DIR__ . '/vendor/autoload.php';

$resend = Resend::client('re_xxxxxxxxx');

$resend->emails->send([
  'from' => 'Acme <onboarding@resend.dev>',
  'to' => ['delivered@resend.dev'],
  'subject' => 'hello world',
  'html' => '<strong>it works!</strong>',
]);
```
