+
+## Asset Management & npm
+
+This project uses `npm` for frontend dependencies (e.g., Bootstrap).
+
+1. Initialize/Install: `npm install`
+2. Add custom CSS/JS in `public/css/app.css` and `public/js/app.js`.
+3. Reference assets in `app/Views/layouts/main.php`.
+
+## How It Works
+
+1.  **Request Flow**: Requests hit `public/index.php`.
+2.  **Initialization**: `Core\Application` initializes `Request`, `Response`, `Router`, and `View`.
+3.  **Routing**: The `Router` matches the `Request` path against registered routes.
+4.  **Dispatching**: If a match is found, the `Router` instantiates the controller and invokes the requested method.
+5.  **Controller Action**: The controller handles business logic and returns a `View` using `$this->render()`.
+6.  **Response**: `View` loads the layout from `app/Views/layouts/main.php`, injects the view content into the `{{content}}` placeholder, and returns the response.
+
+## Adding a New Route
+
+In `public/index.php`, register a route mapping a path to a controller method:
+
+```php
+$app->router->get('/path', [ControllerClass::class, 'methodName']);
+```
+
+## API Routing
+
+API routes are registered in `public/index.php` with the `/api/` prefix to keep them separate from regular page routes.
+
+### Example API Route
+
+```php
+$app->router->get('/api/ping', [App\Controllers\ApiController::class, 'ping']);
+```
+
+### API Controller
+
+The `ApiController` class lives in `app/Controllers/ApiController.php` and should contain methods for API endpoints.
+
+Example:
+```php
+<?php
+namespace App\Controllers;
+
+use Core\Controller;
+
+class ApiController extends Controller
+{
+    public function ping()
+    {
+        // Simple health-check endpoint
+        $this->response->setHeader('Content-Type', 'application/json');
+        $this->response->setBody(json_encode(['status' => 'ok', 'time' => microtime(true)]));
+    }
+}
+```
+
+### Testing the API
+
+You can test the `/api/ping` endpoint with:
+```bash
+curl http://localhost/api/ping
+```
+
+Expected response:
+```json
+{"status":"ok","time":1718409600.123}
+```
