 # 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.

 ## Prerequisites
 
-1.	The samples depend on the Java JDK 1.8 and are built using Maven. You can [download Maven](https://maven.apache.org/download.cgi). [Install and configure Maven](https://maven.apache.org/install.html). The sample require Maven version > 3.3.9. 
-2.	You need an Azure Subscription, if you do not have one - create a [free account](https://azure.microsoft.com/free/?ref=microsoft.com&utm_source=microsoft.com&utm_medium=docs&utm_campaign=visualstudio) before you begin
