+## Install HDInsight applications on clusters
+
+An HDInsight application is an application that users can install on a Linux-based HDInsight cluster. You can use applications provided by Microsoft, third parties, or that you develop yourself. For more information, see [Install third-party Hadoop applications on Azure HDInsight](hdinsight-apps-install-applications.md).
+
+Most of the HDInsight applications are installed on an empty edge node.  An empty edge node is a Linux virtual machine with the same client tools installed and configured as in the head node. You can use the edge node for accessing the cluster, testing your client applications, and hosting your client applications. For more information, see [Use empty edge nodes in HDInsight](hdinsight-apps-use-edge-node.md).
+
 ## Configure cluster size
 
 You are billed for node usage for as long as the cluster exists. Billing starts when a cluster is created and stops when the cluster is deleted. Clusters can’t be de-allocated or put on hold.

 ## Advanced settings: Script actions
 
 You can install additional components or customize cluster configuration by using scripts during creation. Such scripts are invoked via **Script Action**, which is a configuration option that can be used from the Azure portal, HDInsight Windows PowerShell cmdlets, or the HDInsight .NET SDK. For more information, see [Customize HDInsight cluster using Script Action](hdinsight-hadoop-customize-cluster-linux.md).
