 # RabbitMQ Documentation
 
-Welcome to RabbitMQ documentation. RabbitMQ is a reliable and mature messaging and streaming broker, which is easy to deploy on cloud environments, on-premises, and on your local machine. With support for many different messaging protocols, it can scale from providing point-to-point messaging all the way up to globally distributed highly-available event streaming with rock-solid reliability. RabbitMQ is currently used by millions worldwide. 
+Welcome to RabbitMQ documentation. Use the drop-down menu on the top right of any page to select the documentation version for the RabbitMQ release that you are using. We update each version of documentation with the latest minor and patch information for that release.
 
 ## How to use this documentation
 
-Use the navigation on the left to browse through documentation for your release of RabbitMQ. This table of contents is structured so it can be used by our two main RabbitMQ personas: Developer and Administrator.

-Each developer scenario is different depending on the use case. For example, lets take the task of opening a connection, this route differs a lot depending on the messaging protocol a developers uses. This is just one factor, there are many more. You might want to start with [Getting Started](/tutorials), which is a set of tutorials that will guide you on how to use RabbitMQ with AMQP. If you need more details, then go the **How to Use RabbitMQ** section.

+## If you are an Administrator
 
-Each administrator scenario is also different depending on the use case. For administrators, the sequence might usually be install, configure, and monitor. As a recommendation only, start with **Install and Upgrade** documentation on the left, then access the **How to Manage RabbitMQ** tasks, and finally **How to Monitor RabbitMQ**. 
+The table of contents for administrators is structured this way:
 
+ - The **How to Manage RabbitMQ** section provides documentation for configuring and managing the RabbitMQ broker. 
+ The **How to Monitor RabbitMQ** section includes information which will guide you on how to setup monitoring for RabbitMQ and they applications that use it.
