+### Install
+
+Require this package with composer using the following command:
+```bash
+composer require clarification/sendgrid-laravel-driver
+```
+
+After updating composer, add the service provider to the `providers` array in `config/app.php`
+```php
+Clarification\MailDrivers\Sendgrid\SendgridServiceProvider::class,
+```
+
+You will also need to add the sendgrid API Key settings to the array in `config/services.php` and set up the environment key
+```php
+'sendgrid' => [
+    'api_key' => env('SENDGRID_API_KEY'),
+],
+```
+```bash
+SENDGRID_API_KEY=__Your_key_here__
+```
+
+Finally you need to set your mail driver to `sendgrid`. You can do this by changing the driver in `config/mail.php`
+```php
+'driver' => env('MAIL_DRIVER', 'sendgrid'),
+```
+
+Or by setting the environment variable `MAIL_DRIVER` in your .env file
+```bash
+MAIL_DRIVER=sendgrid
+```
