 Begin by installing this package through Composer. Require it directly from the Terminal to take the last stable version:
 ```bash
-$ composer require fedeisas/laravel-mail-css-inliner
+composer require fedeisas/laravel-mail-css-inliner
 ```
 
 At this point the inliner should be already working with the default options. If you want to fine-tune these options, you can do so by publishing the configuration file:
 ```bash
-$ php artisan vendor:publish --provider='Fedeisas\LaravelMailCssInliner\LaravelMailCssInlinerServiceProvider'
+php artisan vendor:publish --provider='Fedeisas\LaravelMailCssInliner\LaravelMailCssInlinerServiceProvider'
 ```
 and changing the settings on the generated `config/css-inliner.php` file.
