+## Usage of Namespaces
+
+The flash messenger supports namespaces.
+This allows to render messages of different types in different places.
+
+### Create Flash Messages for Different Namespaces
+
+Store a `success` message in the messenger of a controller action:
+
+```php
+$this->flashMessenger()->addSuccessMessage('…');
+```
+
+Store an `info` message in the messenger of a controller action:
+
+```php
+$this->flashMessenger()->addInfoMessage('…');
+```
+
+Store a `warning` message in the messenger of a controller action:
+
+```php
+$this->flashMessenger()->addWarningMessage('…');
+```
+
+Store an `error` message in the messenger of a controller action:
+
+```php
+$this->flashMessenger()->addErrorMessage('…');
+```
+
+### Render Flash Messages for Different Namespaces
+
+Render all added `success` messages in a view script:
+
+<!-- markdownlint-disable MD038 MD009 MD046 -->
+=== "Name Usage"
+    ```php
+    <?= $this->flashMessenger()->render('success') ?>
+    ```
+
+=== "Constant Usage"
+    ```php
+    <?= $this->flashMessenger()->render(
+      Laminas\Mvc\Plugin\FlashMessenger\FlashMessenger::NAMESPACE_SUCCESS
+    ) ?>
+    ```
+<!-- markdownlint-restore -->
+
+Render all added `info` messages in a view script:
+
+<!-- markdownlint-disable MD038 MD009 MD046 -->
+=== "Name Usage"
+    ```php
+    <?= $this->flashMessenger()->render('info') ?>
+    ```
+
+=== "Constant Usage"
+    ```php
+    <?= $this->flashMessenger()->render(
+      Laminas\Mvc\Plugin\FlashMessenger\FlashMessenger::NAMESPACE_INFO
+    ) ?>
+    ```

+    ```
+
+=== "Constant Usage"
+    ```php
+    <?= $this->flashMessenger()->render(
+      Laminas\Mvc\Plugin\FlashMessenger\FlashMessenger::NAMESPACE_WARNING
+    ) ?>
+    ```
+<!-- markdownlint-restore -->

+<!-- markdownlint-disable MD038 MD009 MD046 -->
+=== "Name Usage"
+    ```php
+    <?= $this->flashMessenger()->render('error') ?>

+    <?= $this->flashMessenger()->render(
+      Laminas\Mvc\Plugin\FlashMessenger\FlashMessenger::NAMESPACE_ERROR
+    ) ?>
+    ```
+<!-- markdownlint-restore -->
+
+### Use Default Namespace
+
+The flash messenger supports a default namespace which does not represent an explicit status.
+
+Store a `default` message in the messenger of a controller action:
+
+```php
+$this->flashMessenger()->addMessage('…');
+```
+
+Render all added `default` messages in a view script:
+
+```php
+<?= $this->flashMessenger()->render() ?>
+```
