@@ -271,35 +271,13 @@ Since PHP 8.1, fibers are introduced to PHP.
 This means that you can use any fiber based PSR-18 client in order to send async calls.
 
 Here is a short example for `react/http` in combination with `react/async`.
-Your PSR-18 client might look like this:
 
-```php
-use Http\Client\HttpClient;
-use Psr\Http\Message\RequestInterface;
-use Psr\Http\Message\ResponseInterface;
-use React\Http\Browser;
-use function React\Async\await;
+```sh
+composer require react/async veewee/psr18-react-browser
+```
 
-final class AsyncPsr18Browser implements HttpClient
-{
-    public function __construct(
-        private Browser $browser
-    ){
-    }
+*(There currently is no official fiber based PSR-18 implementation of either AMP or ReactPHP. Therefore, [a small bridge can be used intermediately](https://github.com/veewee/psr18-react-browser))*
 
-    public function sendRequest(RequestInterface $request): ResponseInterface
-    {
-        return await(
-            $this->browser->request(
-                $request->getMethod(),
-                (string) $request->getUri(),
-                $request->getHeaders(),
-                (string) $request->getBody()
-            )
-        );
