 ## Key Features
 
 **Unified Elasticsearch API**  
-This project provides a trait-based interface (`ElasticClientApi`) that aggregates the core functionalities of Elasticsearch: indexing, searching, scrolling, updating, deleting, mapping, aliases, refreshing, and [more](documentation/client/README.md). This design abstracts the underlying client implementation and ensures compatibility across different Elasticsearch versions.

 By relying on these concrete implementations, developers can switch between versions with minimal changes to their business logic.

 **High-Performance Bulk API with Akka Streams**  
 Bulk operations leverage the power of Akka Streams to efficiently process and index large volumes of data. This stream-based approach improves performance, resilience, and backpressure handling, especially for real-time or high-throughput indexing scenarios.
 
+**Scroll API with automatic Scroll Strategy detection**  
+The Scroll API is also integrated with Akka Streams, enabling efficient retrieval of large datasets in a streaming fashion. This allows applications to process search results incrementally, reducing memory consumption and improving responsiveness.
+It automatically selects the optimal scrolling strategy (PIT + search_after, search_after, or classic scroll) based on your query and Elasticsearch version.

 **Akka Persistence Integration**  
 The project offers seamless integration with Akka Persistence. This enables Elasticsearch indices to be updated reactively based on persistent events, offering a robust pattern for event-sourced systems.
 
 ## Roadmap
 
-Future enhancements include expanding the SQL parser to support additional operations such as `INSERT`, `UPDATE`, and `DELETE`. The long-term vision is to deliver a fully functional, open-source **JDBC connector for Elasticsearch**, empowering users to interact with their data using standard SQL tooling.
