+### Mailtrap Transport
+
+To use the [Mailtrap](https://mailtrap.io/) driver, install Mailtrap’s PHP SDK via Composer:
+
+    # With symfony http client (recommended)
+    composer require railsware/mailtrap-php symfony/http-client nyholm/psr7
+
+    # Or with guzzle http client
+    composer require railsware/mailtrap-php guzzlehttp/guzzle php-http/guzzle7-adapter
+
+After installing the package, go to your application’s .env file and specify the *MAIL_MAILER* variable as *mailtrap*. Then, define *MAILTRAP_HOST* and *MAILTRAP_API_KEY*, as shown below:
+
+    MAIL_MAILER="mailtrap"
+    # for transactional emails
+    MAILTRAP_HOST="send.api.mailtrap.io"
+    MAILTRAP_API_KEY="YOUR_API_KEY_HERE"
+    # for bulk email sending 
+    MAILTRAP_HOST="bulk.api.mailtrap.io"
+    MAILTRAP_API_KEY="YOUR_API_KEY_HERE"
+
+Lastly, add Mailtrap to the mailers array in your application's main configuration file (e.g., config/mail.php), like so:
+
+    'mailers' => [
+
+                // start mailtrap transport
+                'mailtrap' => [
+                    'transport' => 'mailtrap'
+                ],
+                // end mailtrap transport
+
+        ]
+
+To learn more about Mailtrap and see examples, read the [Mailtrap driver documentation](https://github.com/railsware/mailtrap-php/tree/main/src/Bridge/Laravel#usage).
