-## Overview
+A simple lifecycle manager for long-running Rust applications. Run multiple services concurrently with graceful shutdown handling.
-
-MAD is a robust lifecycle manager designed for long-running Rust operations. It provides a simple, composable way to manage multiple concurrent services within your application, handling graceful startup and shutdown automatically.
-
-### Perfect for:
-- 🌐 Web servers
-- 📨 Queue consumers and message processors  
-- 🔌 gRPC servers
-- ⏰ Cron job runners
-- 🔄 Background workers
-- 📡 Any long-running async operations
-
-## Features
-
-- **Component-based architecture** - Build your application from composable, reusable components
-- **Graceful shutdown** - Automatic handling of shutdown signals with proper cleanup
-- **Concurrent execution** - Run multiple components in parallel with tokio
-- **Error handling** - Built-in error propagation and logging
-- **Cancellation tokens** - Coordinate shutdown across all components
-- **Minimal boilerplate** - Focus on your business logic, not lifecycle management
 
 ## Installation
 
-Add MAD to your `Cargo.toml`:
-
 ```toml
 [dependencies]
-notmad = "0.7.5"
+notmad = "0.10.0"
 tokio = { version = "1", features = ["full"] }
-async-trait = "0.1"
 ```
 
 ## Quick Start
 
-Here's a simple example of a component that simulates a long-running server:
-
 ```rust
-use mad::{Component, Mad};
+use notmad::{Component, Mad};
-use async_trait::async_trait;
 use tokio_util::sync::CancellationToken;
 
-// Define your component
+struct MyService;
-struct WebServer {
-    port: u16,
-}
-
-#[async_trait]
-impl Component for WebServer {
-    fn name(&self) -> Option<String> {
-        Some(format!("WebServer on port {}", self.port))
-    }
-
-    async fn run(&self, cancellation: CancellationToken) -> Result<(), mad::MadError> {
-        println!("Starting web server on port {}", self.port);
-        
-        // Your server logic here
-        // The cancellation token will be triggered on shutdown
-        tokio::select! {
-            _ = cancellation.cancelled() => {
-                println!("Shutting down web server");
-            }
-            _ = self.serve() => {
-                println!("Server stopped");
-            }
-        }
 
+impl Component for MyService {
+    async fn run(&self, cancellation: CancellationToken) -> Result<(), notmad::MadError> {
+        println!("Service running...");
+        cancellation.cancelled().await;
+        println!("Service stopped");
         Ok(())
     }
 }
 
-impl WebServer {
-    async fn serve(&self) {
-        // Simulate a running server
-        tokio::time::sleep(std::time::Duration::from_secs(3600)).await;
-    }
-}
-
 #[tokio::main]
 async fn main() -> anyhow::Result<()> {
-    // Build and run your application
     Mad::builder()
-        .add(WebServer { port: 8080 })
+        .add(MyService)
-        .add(WebServer { port: 8081 })  // You can add multiple instances
         .run()
         .await?;
-
     Ok(())
 }
 ```
 
-## Advanced Usage
+## Basic Usage
 
-### Custom Components
+### Axum Web Server with Graceful Shutdown
 
-Components can be anything that implements the `Component` trait:
+Here's how to run an Axum server with MAD's graceful shutdown:
 
 ```rust
-use mad::{Component, Mad};
+use axum::{Router, routing::get};
-use async_trait::async_trait;
+use notmad::{Component, ComponentInfo};
+use tokio_util::sync::CancellationToken;
 
-struct QueueProcessor {
+struct WebServer {
-    queue_name: String,
+    port: u16,
 }
 
-#[async_trait]
+impl Component for WebServer {
-impl Component for QueueProcessor {
+    fn info(&self) -> ComponentInfo {
-    fn name(&self) -> Option<String> {
+        format!("WebServer:{}", self.port).into()
-        Some(format!("QueueProcessor-{}", self.queue_name))
     }
 
-    async fn run(&self, cancellation: CancellationToken) -> Result<(), mad::MadError> {
+    async fn run(&self, cancel: CancellationToken) -> Result<(), notmad::MadError> {
-        while !cancellation.is_cancelled() {
+        let app = Router::new().route("/", get(|| async { "Hello, World!" }));
-            // Process messages from queue
+
-            self.process_next_message().await?;
+        let listener = tokio::net::TcpListener::bind(format!("0.0.0.0:{}", self.port))
-        }
+            .await?;
+
+        println!("Listening on http://0.0.0.0:{}", self.port);
+
+        // Run server with graceful shutdown
+        axum::serve(listener, app)
+            .with_graceful_shutdown(async move {
+                cancel.cancelled().await;
+                println!("Shutting down server...");
+            })
+            .await?;
+
         Ok(())
     }
 }
 ```
 
-### Error Handling
+### Run Multiple Services
-
-MAD provides comprehensive error handling through the `MadError` type with automatic conversion from `anyhow::Error`:
 
 ```rust
-async fn run(&self, cancellation: CancellationToken) -> Result<(), mad::MadError> {
+Mad::builder()
-    // Errors automatically convert from anyhow::Error to MadError
+    .add(WebServer { port: 8080 })
-    database_operation().await?;
+    .add(WebServer { port: 8081 })
+    .run()
+    .await?;
+```
 
-    // Or return explicit errors
+### Use Functions as Components
-    if some_condition {
+
-        return Err(anyhow::anyhow!("Something went wrong").into());
+```rust
+Mad::builder()
+    .add_fn(|cancel| async move {
+        println!("Running...");
+        cancel.cancelled().await;
+        Ok(())
+    })
+    .run()
+    .await?;
+```
+
+## Lifecycle Hooks
+
+Components support optional setup and cleanup phases:
+
+```rust
+impl Component for DatabaseService {
+    async fn setup(&self) -> Result<(), notmad::MadError> {
+        println!("Connecting to database...");
+        Ok(())
     }
 
-    Ok(())
+    async fn run(&self, cancel: CancellationToken) -> Result<(), notmad::MadError> {
+        cancel.cancelled().await;
+        Ok(())
+    }
+
+    async fn close(&self) -> Result<(), notmad::MadError> {
+        println!("Closing database connection...");
+        Ok(())
+    }
 }
 ```
 
+## Migration from v0.9
+
+### Breaking Changes
+
+1. **`name()` → `info()`**: Returns `ComponentInfo` instead of `Option<String>`
+   ```rust
+   // Before
+   fn name(&self) -> Option<String> { Some("my-service".into()) }
+
+   // After
+   fn info(&self) -> ComponentInfo { "my-service".into() }
+   ```
+
+2. **No more `async-trait`**: Remove the dependency and `#[async_trait]` attribute
+   ```rust
+   // Before
+   #[async_trait]
+   impl Component for MyService { }
+
+   // After
+   impl Component for MyService { }
+   ```
+

 //! # MAD - Lifecycle Manager for Rust Applications
 //!
-//! MAD is a robust lifecycle manager designed for long-running Rust operations. It provides
+//! A simple lifecycle manager for long-running Rust applications. Run multiple services
-//! a simple, composable way to manage multiple concurrent services within your application,
+//! concurrently with graceful shutdown handling.
-//! handling graceful startup and shutdown automatically.
-//!
-//! ## Overview
-//!
-//! MAD helps you build applications composed of multiple long-running components that need
-//! to be orchestrated together. It handles:
-//!
-//! - **Concurrent execution** of multiple components
-//! - **Graceful shutdown** with cancellation tokens
-//! - **Error aggregation** from multiple components
-//! - **Lifecycle management** with setup, run, and close phases
 //!
 //! ## Quick Start
 //!
 //! ```rust,no_run
 //! use notmad::{Component, Mad};
-//! use async_trait::async_trait;
 //! use tokio_util::sync::CancellationToken;
 //!

 //!
-//! ## Component Lifecycle
+//! ## Features
 //!
-//! Components go through three phases:
+//! - Run multiple components concurrently
-//!
+//! - Graceful shutdown with cancellation tokens
-//! 1. **Setup**: Optional initialization phase before components start running
+//! - Optional lifecycle hooks: `setup()`, `run()`, `close()`
-//! 2. **Run**: Main execution phase where components perform their work
+//! - Automatic error aggregation
-//! 3. **Close**: Optional cleanup phase after components stop
+//! - SIGTERM and Ctrl+C signal handling
-//!
-//! ## Error Handling
-//!
-//! MAD provides comprehensive error handling through [`MadError`], which can:
-//! - Wrap errors from individual components
-//! - Aggregate multiple errors when several components fail
-//! - Automatically convert from `anyhow::Error`
-//!
-//! ## Shutdown Behavior
-//!
-//! MAD handles shutdown gracefully:
-//! - Responds to SIGTERM and Ctrl+C signals
-//! - Propagates cancellation tokens to all components
-//! - Waits for components to finish cleanup
-//! - Configurable cancellation timeout
