 # Frontend Integration
 
-Once the backend logic is in place, the custom shipping carrier will automatically appear in the Mage-OS checkout if it's enabled and configured properly. The title and price will be displayed as defined in the carrier configuration.

 # Conclusion
-This guide walks through the basic setup of a custom shipping carrier in Mage-OS. The carrier integrates with Mage-OS’s shipping framework, allowing you to customize the shipping calculation and display it during the checkout process. You can extend this basic structure to integrate with third-party APIs, offer dynamic shipping rates, or introduce more complex shipping logic based on cart contents or customer information.
