-- Webservers
+## Overview
-- Queue bindings
-- gRPC servers etc
-- Cron runners
 
-It is supposed to be the main thing the application runs, and everything from it is spawned and managed by it.
+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"
+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
-struct WaitServer {}
+use mad::{Component, Mad};
+use async_trait::async_trait;
+use tokio_util::sync::CancellationToken;
+
+// Define your component
+struct WebServer {
+    port: u16,
+}
 
 #[async_trait]
-impl Component for WaitServer {
+impl Component for WebServer {
     fn name(&self) -> Option<String> {
-        Some("NeverEndingRun".into())
+        Some(format!("WebServer on port {}", self.port))
     }
 
     async fn run(&self, cancellation: CancellationToken) -> Result<(), mad::MadError> {
-        let millis_wait = rand::thread_rng().gen_range(50..1000);
+        println!("Starting web server on port {}", self.port);
-
+        
-        // Simulates a server running for some time. Is normally supposed to be futures blocking indefinitely
+        // Your server logic here
-        tokio::time::sleep(std::time::Duration::from_millis(millis_wait)).await;
+        // The cancellation token will be triggered on shutdown
-
+        tokio::select! {
+            _ = cancellation.cancelled() => {
+                println!("Shutting down web server");
+            }
+            _ = self.serve() => {
+                println!("Server stopped");
+            }
+        }
+        
         Ok(())
     }
 }
 
+impl WebServer {
+    async fn serve(&self) {
+        // Simulate a running server
+        tokio::time::sleep(std::time::Duration::from_secs(3600)).await;
+    }
+}
+
 #[tokio::main]

+## Advanced Usage
+
+### Custom Components
+
+Components can be anything that implements the `Component` trait:
+
+```rust
+use mad::{Component, Mad};
+use async_trait::async_trait;
+
+struct QueueProcessor {
+    queue_name: String,
+}
+
+#[async_trait]
+impl Component for QueueProcessor {
+    fn name(&self) -> Option<String> {
+        Some(format!("QueueProcessor-{}", self.queue_name))
+    }
+
+    async fn run(&self, cancellation: CancellationToken) -> Result<(), mad::MadError> {
+        while !cancellation.is_cancelled() {
+            // Process messages from queue
+            self.process_next_message().await?;
+        }
+        Ok(())
+    }
+}
+```
+
+### Error Handling
+
+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> {
+    // Errors automatically convert from anyhow::Error to MadError
+    database_operation().await?;
+    
+    // Or return explicit errors
+    if some_condition {
+        return Err(anyhow::anyhow!("Something went wrong").into());
+    }
+    
+    Ok(())
+}
+```
