+## Attribute-Based Routing
+
+Modern PHP 8+ attribute-based routing allows you to define routes directly on controller methods using PHP attributes, providing a modern alternative to YAML configuration files.
+
+### Basic Usage
+
+#### Simple Route
+
+```php
+use Neuron\Routing\Attributes\Get;
+
+class HomeController
+{
+    #[Get('/')]
+    public function index()
+    {
+        return 'Hello World';
+    }
+}
+```
+
+#### HTTP Method Attributes
+
+```php
+use Neuron\Routing\Attributes\Get;
+use Neuron\Routing\Attributes\Post;
+use Neuron\Routing\Attributes\Put;
+use Neuron\Routing\Attributes\Delete;
+
+class UsersController
+{
+    #[Get('/users')]
+    public function index() { }
+
+    #[Get('/users/:id')]
+    public function show(int $id) { }
+
+    #[Post('/users')]
+    public function store() { }
+
+    #[Put('/users/:id')]
+    public function update(int $id) { }
+
+    #[Delete('/users/:id')]
+    public function destroy(int $id) { }
+}
+```
+
+#### Route Names and Filters
+
+```php
+#[Get('/admin/users', name: 'admin.users.index', filters: ['auth'])]
+public function index() { }
+
+#[Post('/admin/users', name: 'admin.users.store', filters: ['auth', 'csrf'])]
+public function store() { }
+```
+
+#### Route Groups
+
+Apply common settings to all routes in a controller:
+
+```php
+use Neuron\Routing\Attributes\RouteGroup;
+use Neuron\Routing\Attributes\Get;
+use Neuron\Routing\Attributes\Post;
+
+#[RouteGroup(prefix: '/admin', filters: ['auth'])]
+class AdminController
+{
+    #[Get('/dashboard')]  // Becomes /admin/dashboard with 'auth' filter
+    public function dashboard() { }
+
+    #[Post('/users', filters: ['csrf'])]  // Becomes /admin/users with ['auth', 'csrf'] filters
+    public function createUser() { }
+}
+```
+
+#### Multiple Routes on Same Method
+
+```php
+#[Get('/api/v1/users')]
+#[Get('/api/v2/users')]
+public function getUsers()
+{
+    // Handle both API versions
+}
+```
+
+### Configuration
+
+#### Enable Attribute Routing in MVC Application
+
+Add controller paths to your `config/neuron.yaml`:
+
+```yaml
+routing:
+  controller_paths:
+    - path: 'src/Controllers'
+      namespace: 'App\Controllers'
+    - path: 'src/Admin/Controllers'
+      namespace: 'App\Admin\Controllers'
+```
+
+#### Hybrid Approach (YAML + Attributes)
+
+You can use both YAML routes and attribute routes together:
+
+- **YAML routes**: Legacy routes, package-provided routes
+- **Attribute routes**: New application routes
+
+The MVC Application will load both automatically.
+
+### Benefits
+
+- **Co-location**: Routes live with controller logic
+- **Type Safety**: IDE autocomplete and validation
+- **Refactor-Friendly**: Routes update when controllers change
+- **No Sync Issues**: Can't have orphaned routes
+- **Modern Standard**: Used by Symfony, Laravel, ASP.NET, Spring Boot
+- **Self-Documenting**: Route definition IS the documentation
+
+### Performance
+
+Route scanning uses PHP Reflection, which could be slow. For production:
+
+1. Routes are scanned once during application initialization
+2. The Router caches RouteMap objects in memory
+3. No reflection happens during request handling
+4. Future: Add route caching to file for zero-cost production routing
+
+### Migration from YAML
+
+**Before (YAML):**
+```yaml
+# routes.yaml
+home:
+  method: GET
+  route: /
+  controller: App\Controllers\Home@index
+```
+
+**After (Attributes):**
+```php
+class Home
+{
+    #[Get('/', name: 'home')]
+    public function index() { }
+}
+```
+
+See `tests/unit/RouteScannerTest.php` for working examples of basic route definition, route groups with prefixes, filter composition, and multiple routes per method.
