 # Spring Dynamic Microservices
-
-
 This is a comprehensive **Java-based microservices system** built with Spring Boot 3.x and Spring Cloud. It demonstrates dynamic service registration, routing, and payment processing using a modular architecture. The project includes CI integration with GitHub Actions and code quality checks with SonarCloud and JaCoCo.
 
-### Modules
+#### Architecture Overview
+- **eureka-server**: Acts as the service registry for all microservices.
+- **gateway-service**: A Spring Cloud Gateway-based API Gateway that routes requests dynamically to microservices.
+- **payment-service-paypal**: A microservice simulating PayPal payment logic, registered with Eureka.
+- **payment-service-stripe**: A microservice simulating Stripe payment logic, registered with Eureka.
+- **docker-compose.yml**: Boots up all services with required ports and network for full-stack integration.
+
+All services are **auto-discovered via Eureka** and routed through **Spring Cloud Gateway** without hardcoded endpoints.
 
+#### Modules
 - `common-api` – Shared domain objects, constants, and utilities.
 - `eureka-server` – Service discovery server powered by Netflix Eureka.
 - `gateway-service` – Spring Cloud Gateway for dynamic routing and API exposure.
 - `payment-service-paypal` – PayPal-specific payment microservice.
 - `payment-service-stripe` – Stripe-specific payment microservice.
