 ## Configuration
-To change the default drip interval of 5 minutes, simply publish the configuration file:
+The following elements are configurable:
+- **domain:** (default: `url('/')`) Change to point to a different domain than
+ your app. This is useful if you are behind a proxy or load-balancer.
+- **route:** (default: `genealabs/laravel-caffeine/drip`) Change to customize
+ the drip URL in the browser. This is just cosmetic.
+- **dripIntervalInMilliSeconds:** (default: 5 mins) Change to configure the drip
+ interval.
+
+You only need to publish the config file it you want to customize it:
 ```sh
 php artisan vendor:publish --tag=genealabs-laravel-caffeine
 ```
 
 You can now change the default value in `/app/config/genealabs-laravel-caffeine.php` as desired. Deleting the
-`/app/config/genealabs-laravel-caffeine.php` file will revert back to the default 5-minute interval.
+`/app/config/genealabs-laravel-caffeine.php` file will revert back to the default settings.
 
 ## Usage
 That was it! It will apply itself automatically where it finds a form with a `_token` field, or a meta tag named
