+    Amazon Redshift **Overview**
+    This is an interface reference for Amazon Redshift. It contains
+    documentation for one of the programming or command line
+    interfaces you can use to manage Amazon Redshift clusters. Note
+    that Amazon Redshift is asynchronous, which means that some
+    interfaces may require techniques, such as polling or asynchronous
+    callback handlers, to determine when a command has been applied.
+    In this reference, the parameter descriptions indicate whether a
+    change is applied immediately, on the next instance reboot, or
+    during the next maintenance window. For a summary of the Amazon
+    Redshift cluster management interfaces, go to `Using the Amazon
+    Redshift Management Interfaces `_.
+
+    Amazon Redshift manages all the work of setting up, operating, and
+    scaling a data warehouse: provisioning capacity, monitoring and
+    backing up the cluster, and applying patches and upgrades to the
+    Amazon Redshift engine. You can focus on using your data to
+    acquire new insights for your business and customers.
+
+    If you are a first-time user of Amazon Redshift, we recommend that
+    you begin by reading the The `Amazon Redshift Getting Started
+    Guide`_
+
+    If you are a database developer, the `Amazon Redshift Database
+    Developer Guide`_ explains how to design, build, query, and
+    maintain the databases that make up your data warehouse.
