## Overview

Pakodi is a restaurant food-ordering application. Its main customer workflow is login, browse restaurants and menu/nutrition details, add items to a basket, and check out into placed orders; customers can also view past orders. Sampled services show the basket-to-order transfer and persistence operations. The README is empty, and controller implementations for menu, restaurant, and checkout were not sampled, so those links follow the named modules in the tree; uncertain wiring is omitted.

Main entry points: [`src/main/java/com/Api/Pakodi/Service/ordersService/CheckOutService.java`](https://github.com/maruthisarathchandra/pakodi/blob/master/src/main/java/com/Api/Pakodi/Service/ordersService/CheckOutService.java) (Checkout service), [`src/main/java/com/Api/Pakodi/Service/ordersService/PakodiBasketService.java`](https://github.com/maruthisarathchandra/pakodi/blob/master/src/main/java/com/Api/Pakodi/Service/ordersService/PakodiBasketService.java) (Basket service), [`src/main/java/com/Api/Pakodi/Service/ordersService/BasketItemsService.java`](https://github.com/maruthisarathchandra/pakodi/blob/master/src/main/java/com/Api/Pakodi/Service/ordersService/BasketItemsService.java) (Basket items service), [`src/main/java/com/Api/Pakodi/Controller/ordersController/BasketController.java`](https://github.com/maruthisarathchandra/pakodi/blob/master/src/main/java/com/Api/Pakodi/Controller/ordersController/BasketController.java) (Basket controller)
