 ## Usage
 
-**`Router`** implements `RequestHandler`. Any attached `RequestHandler` and `Middleware` instances will receive any `ServerObserver` events.
+**`Router`** implements `RequestHandler`, which is used by an [`HttpServer`](https://github.com/amphp/http-server#creating-an-http-server) to handle incoming requests. Incoming requests are routed by `Router` to other `RequestHandler`s based on the request path.
 
-Routes can be defined using the `addRoute($method, $uri, $requestHandler)` method. Please read the [FastRoute documentation on how to define placeholders](https://github.com/nikic/FastRoute#defining-routes).
+Routes can be defined using the `addRoute($method, $uri, $requestHandler, ...$middeware)` method.
+
+```php
+public function addRoute(
+    string $method,
+    string $uri,
+    RequestHandler $requestHandler,
+    Middleware ...$middlewares,
+): void
+```
 
 Matched route arguments are available in the request attributes under the `Amp\Http\Server\Router` key as an associative array.
 
+Middleware provided to `addRoute()` will only be applied to the given route.
+
+Please read the [FastRoute documentation on how to define placeholders](https://github.com/nikic/FastRoute#defining-routes).
+
+### Middleware
+
+In addition to specifying middlewares by route with `addRoute()`, you may wrap all routes with a common set of middlware using `stackMiddleware(...$middleware)`.
+
+```php
+public function stackMiddleware(Middleware ...$middlewares): void
+```
+
+### Fallback
+
+If no routes match a request path, you can specify another instance of `RequestHandler` which will handle any unmatched routes. If no fallback handler is provided, a 404 response will be returned using the instance of `ErrorHandler` provided to the `Router` constructor.
+
+```php
+public function setFallback(RequestHandler $requestHandler): void
+```
+
 ## Example
 
 ```php
-$router = new Router;
+use Amp\Http\HttpStatus;
+use Amp\Http\Server\DefaultErrorHandler;
+use Amp\Http\Server\Request;
+use Amp\Http\Server\RequestHandler\ClosureRequestHandler;
+use Amp\Http\Server\Response;
+use Amp\Http\Server\Router;
+use Amp\Http\Server\SocketHttpServer;
 
-$router->addRoute('GET', '/', new CallableRequestHandler(function () {
-    return new Response(HttpStatus::OK, ['content-type' => 'text/plain'], 'Hello, world!');
-}));
+// $logger is an instance of a PSR-3 logger.
+$server = SocketHttpServer::createForDirectAccess($logger);
+$errorHandler = new DefaultErrorHandler();
 
-$router->addRoute('GET', '/{name}', new CallableRequestHandler(function (Request $request) {
-    $args = $request->getAttribute(Router::class);
-    return new Response(HttpStatus::OK, ['content-type' => 'text/plain'], "Hello, {$args['name']}!");
-}));
+$router = new Router($server, $errorHandler);
+
+$router->addRoute('GET', '/', new ClosureRequestHandler(
+    function () {
+        return new Response(
+            status: HttpStatus::OK,
+            headers: ['content-type' => 'text/plain'],
+            body: 'Hello, world!',
+        );
+    },
+));
+
+$router->addRoute('GET', '/{name}', new ClosureRequestHandler(
+    function (Request $request) {
+        $args = $request->getAttribute(Router::class);
+        return new Response(
+            status: HttpStatus::OK,
+            headers: ['content-type' => 'text/plain'],
+            body: "Hello, {$args['name']}!",
+        );
+    },
+));
+
+$server->expose('0.0.0.0:1337');
+
+$server->start($router, $errorHandler);
+
+// Serve requests until SIGINT or SIGTERM is received by the process.
+Amp\trapSignal([SIGINT, SIGTERM]);
+
+$server->stop();
+```

 ## Limitations
@@ -40,3 +108,11 @@ This will also decode any forward slashes (`/`), which might result in unexpecte
 FastRoute placeholders match path segments by default, which are separated by slashes.
 That means a route like `/token/{token}` won't match if the token contains an encoded slash.
 You can work around this limitation by using a custom regular expression for the placeholder like `/token/{token:.+}`.
