 # Azure Event Hubs Java samples
 
-Azure Event Hubs is a highly scalable data streaming platform and event ingestion service, capable of receiving and processing millions of events per second. The samples present here enables Java developers to easily ingest and process events from your event hub.
+**Note:**: The samples present here enables Java developers to easily ingest and process events from an instance of [Azure Event Hubs](https://docs.microsoft.com/azure/event-hubs/event-hubs-about) using the legacy libraries `com.microsoft.azure:azure-eventhubs` and `com.microsoft.azure:azure-eventhubs-eph`. We strongly recommend you to use the current library `com.azure:azure-messaging-eventhubs` instead.
