+## Advanced Configuration
+
+### Customizing the dio instance
+
+Meilisearch uses [dio](https://pub.dev/packages/dio) internally to send requests, you can provide it with your own interceptors or adapter using the `MeiliSearchClient.withCustomDio` constructor.
+
+### Using MeiliDocumentContainer
+
+The `MeiliDocumentContainer<T>` class contains meilisearch-specific fields (e.g. `rankingScoreDetails`, `_formatted`, `matchesPosition`, etc...).
+
+We define the `mapToContainer()` extension to help you quickly opt-in to this class, example:
+
+```dart
+final res = await index 
+      .search("hello world") 
+      .asSearchResult() //or .asPaginatedResult() if using page parameters
+      .mapToContainer(); 
+```
+
