+Working with Marshaller
+-----------------------
+
+TagAwareMarshaller for Tag-Based Caching
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Optimizes caching for tag-based retrieval, allowing efficient management of related items::
+
+    $marshaller = new TagAwareMarshaller();
+
+    $cache = new RedisAdapter($redis, 'tagged_namespace', 3600, $marshaller);
+
+    $item = $cache->getItem('tagged_key');
+    $item->set(['value' => 'some_data', 'tags' => ['tag1', 'tag2']]);
+    $cache->save($item);
+
+SodiumMarshaller for Encrypted Caching
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Encrypts cached data using Sodium for enhanced security::
+
+    $encryptionKeys = [sodium_crypto_box_keypair()];
+    $marshaller = new SodiumMarshaller($encryptionKeys);
+
+    $cache = new RedisAdapter($redis, 'secure_namespace', 3600, $marshaller);
+
+    $item = $cache->getItem('secure_key');
+    $item->set('confidential_data');
+    $cache->save($item);
+
+DefaultMarshaller with igbinary Serialization
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Uses ``igbinary` for faster and more efficient serialization when available::
+
+    $marshaller = new DefaultMarshaller(true);
+
+    $cache = new RedisAdapter($redis, 'optimized_namespace', 3600, $marshaller);
+
+    $item = $cache->getItem('optimized_key');
+    $item->set(['data' => 'optimized_data']);
+    $cache->save($item);
+
+DefaultMarshaller with Exception on Failure
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Throws an exception if serialization fails, facilitating error handling::
+
+    $marshaller = new DefaultMarshaller(false, true);
+
+    $cache = new RedisAdapter($redis, 'error_namespace', 3600, $marshaller);
+
+    try {
+        $item = $cache->getItem('error_key');
+        $item->set('data');
+        $cache->save($item);
+    } catch (\ValueError $e) {
+        echo 'Serialization failed: '.$e->getMessage();
+    }
+
+SodiumMarshaller with Key Rotation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Supports key rotation, ensuring secure decryption with both old and new keys::
+
+    $keys = [sodium_crypto_box_keypair(), sodium_crypto_box_keypair()];
+    $marshaller = new SodiumMarshaller($keys);
+
+    $cache = new RedisAdapter($redis, 'rotated_namespace', 3600, $marshaller);
+
+    $item = $cache->getItem('rotated_key');
+    $item->set('data_to_encrypt');
+    $cache->save($item);
