 ## Overview
 
+This guide covers all configuration options for the PSR Bridge extension, from
+basic setup to advanced HTTP message handling, worker mode integration, and
+stateless application configuration.
+
 ## Basic configuration
 
+### Core components setup
+
+Replace the default Yii2 Request and Response components with PSR Bridge
+enhanced versions.
+
+```php
+<?php
+
+declare(strict_types=1);
+
+use yii2\extensions\psrbridge\http\ErrorHandler;
+use yii2\extensions\psrbridge\http\Request;
+use yii2\extensions\psrbridge\http\Response;
+
+return [
+    'components' => [
+        'request' => [
+            'class' => Request::class,
+            'enableCookieValidation' => false,
+            'enableCsrfValidation' => false,
+        ],
+        'response' => [
+            'class' => Response::class,
+        ],
+        'errorHandler' => [
+            'class' => ErrorHandler::class,
+        ],
+    ],
+];
+```
+
+## Error handling configuration
+
+```php
+<?php
+
+declare(strict_types=1);
+
+use yii2\extensions\psrbridge\http\ErrorHandler;
+
+'errorHandler' => [
+    'class' => ErrorHandler::class,
+    'errorAction' => 'site/error',
+    'discardExistingOutput' => true,
+],
+```
+
+### Custom error views and formats
+
+```php
+<?php
+
+declare(strict_types=1);
+
+use yii2\extensions\psrbridge\http\ErrorHandler;
+
+'errorHandler' => [
+    'class' => ErrorHandler::class,
+    'errorView' => '@app/views/error.php',
+    'exceptionView' => '@app/views/exception.php',
+    'callStackItemView' => '@app/views/callStackItem.php',
+    'displayVars' => ['_GET', '_POST', '_FILES', '_COOKIE'],
+],
+```
+
+### Memory management configuration
+
+Configure memory limits and garbage collection behavior.
+
+```php
+<?php
+
+declare(strict_types=1);
+
+use yii2\extensions\psrbridge\http\StatelessApplication;
+
+$app = new StatelessApplication($config);
+
+// Enable logger flushing (default: true)
+$app->flushLogger = true;
+
+// Memory management example
+if ($app->clean()) {
+    // Memory usage exceeded 90% of limit
+    // Trigger worker restart or cleanup
+    exit(0);
+}
+```
+
+### PSR-7 factory dependencies
+
+Configure PSR-7 HTTP message factories for request/response conversion.
+
+```php
+<?php
+
+declare(strict_types=1);
+
+use HttpSoft\Message\ResponseFactory;
+use HttpSoft\Message\ServerRequestFactory;
+use HttpSoft\Message\StreamFactory;
+use HttpSoft\Message\UploadedFileFactory;
+use Psr\Http\Message\ResponseFactoryInterface;
+use Psr\Http\Message\ServerRequestFactoryInterface;
+use Psr\Http\Message\StreamFactoryInterface;
+use Psr\Http\Message\UploadedFileFactoryInterface;
+
+'container' => [
+    'definitions' => [
+        ResponseFactoryInterface::class => ResponseFactory::class,
+        ServerRequestFactoryInterface::class => ServerRequestFactory::class,
+        StreamFactoryInterface::class => StreamFactory::class,
+        UploadedFileFactoryInterface::class => UploadedFileFactory::class,
+    ],
+],
+```
+
+### StatelessApplication configuration
+
+For worker-based environments (FrankenPHP, RoadRunner).
+
+```php
+<?php
+
+declare(strict_types=1);
+
+use yii2\extensions\psrbridge\http\Request;
+use yii2\extensions\psrbridge\http\Response;
+use yii2\extensions\psrbridge\http\StatelessApplication;
+
+$config = [
+    'id' => 'stateless-app',
+    'basePath' => dirname(__DIR__),
+    'controllerNamespace' => 'app\\controllers',
+    'components' => [
+        'request' => [
+            'class' => Request::class,
+            'workerMode' => true,
+        ],
+        'response' => [
+            'class' => Response::class,
+        ],
+        // ... other components
+    ],
+];
+
+$app = new StatelessApplication($config);
+```
