+### Formatting Numbers
+
+The package by default does not use round to format numbers, and instead returns the number using floatval().
+
+If you'd prefer this number to be rounded, you can customize the formatting in the configuration file.
+
+Defaults to false.
+
+```php
+'format_numbers' => env('LARAVEL_CART_FORMAT_VALUES', false),
+'round_mode' => env('LARAVEL_CART_ROUND_MODE', 'down'),
+```
+
+### Decimals
+
+You can customize the number of decimals in the configuration file.
+
+Defaults to 2.
+
+```php
+'decimals' => env('LARAVEL_CART_DECIMALS', 2),
+```
+
+### Round Mode
+
+The package uses the `round` function to round the prices. You can customize the rounding mode in the configuration file.
+
+Defaults to `down`.
+
+```php
+'round_mode' => env('LARAVEL_CART_ROUND_MODE', 'down'),

+#### Using the `getCalculatedValueForCondition` method on the cart instance

+This method automatically calculates the value of a condition by it's name based on the order of the conditions.
+
+```php
+Cart::add([
+    'id' => 1,
+    'name' => 'Apple iPhone 15',

+
+Cart::getCalculatedValueForCondition('Coupon Discount'); // returns 200
+Cart::getCalculatedValueForCondition('Gift Card'); // returns 0 as the coupon discount is applied first and brings the subtotal to 0

 ### Condition on items
 
 Item conditions are useful if you have discounts to be applied specifically on an item and not on the whole cart value.
