+//! # Services
+//!
+//! This module contains the business logic of the application. Services orchestrate the
+//! interaction between models, repositories, and other components to fulfill specific use
+//! cases.
+//!
+//! They define the core operations that the application performs and are responsible for
+//! enforcing business rules and ensuring data consistency.
+//!
+//! Example:
+//!
+//! ```
+//! // A service for managing newsletter subscriptions
+//! pub struct NewsletterService {
+//!     // ... dependencies (e.g., SubscriberRepository, EmailClient)
+//! }
+//!
+//! impl NewsletterService {
+//!     // Method to subscribe a user to the newsletter
+//!     pub async fn subscribe_user(&self, email: &str, name: &str) -> Result<(), String> {
+//!         // ... business logic (e.g., validate email, create subscriber, send confirmation email)
+//!         Ok(())
+//!     }
+//! }
+//! ```
