+## Storing Settings
+
+NativePHP offers an easy method to store and retrieve settings in your application. This is helpful for saving application-wide
+settings that persist even after closing and reopening the application.
+
+Settings are managed using the `Settings` facade and are stored in a file named `config.json` in the
+[`appdata`](/docs/getting-started/debugging#start-from-scratch) directory of your application.
+
+```php
+use Native\Laravel\Facades\Settings;
+```
+
+### Setting a value
+It's as simple as calling the `set` method. The key must be a string.
+```php
+Settings::set('key', 'value');
+```
+
+### Getting a value
+To retrieve a setting, use the `get` method.
+```php
+$value = Settings::get('key');
+```
+
+You may also provide a default value to return if the setting does not exist.
+```php
+$value = Settings::get('key', 'default');
+```
+If the setting does not exist, `default` will be returned.
+
+### Forgetting a value
+If you want to remove a setting altogether, use the `forget` method.
+```php
+Settings::forget('key');
+```
+
+### Clearing all settings
+To remove all settings, use the `clear` method.
+```php
+Settings::clear();
+```
+This will remove all settings from the `config.json` file.
+
+## Events
+
+### `SettingChanged`
+The `Native\Laravel\Events\Notifications\SettingChanged` event is dispatched when a setting is changed.
+
+Example usage:
+```php
+Event::listen(SettingChanged::class, function (SettingChanged $event) {
+    $key = $event->key; // Key of the setting that was changed
+    $value = $event->value; // New value of the setting
+});
+```
+
+This event can also be listened with Livewire to refresh your settings page:
+```php
+use Livewire\Component;
+use Native\Laravel\Events\Notifications\SettingChanged;
+
+class Settings extends Component
+{
+    protected $listeners = [
+        'native:'.SettingChanged::class => '$refresh',
+    ];
+}
+```
+
