 # drush-drupal-settings
  Allows you to get values for read only settings that are stored in settings.php (drush 9.3 and newer)
+
+## Installation
+
+```
+composer require nymedia/drupal_settings
+```
+
+## Usage
+
+Imagine we have a settings.local.php that includes this:
+
+```php
+$settings['environment'] = 'development';
+```
+
+Now maybe we want to get ahold of this value in a bash script, or a composer script. We could just go ahead and use this package:
+
+```
+drush setting:get environment
+```
