+    AWS CloudFormation
+    AWS CloudFormation enables you to create and manage AWS
+    infrastructure deployments predictably and repeatedly. AWS
+    CloudFormation helps you leverage AWS products such as Amazon EC2,
+    EBS, Amazon SNS, ELB, and Auto Scaling to build highly-reliable,
+    highly scalable, cost effective applications without worrying
+    about creating and configuring the underlying AWS infrastructure.
+
+    With AWS CloudFormation, you declare all of your resources and
+    dependencies in a template file. The template defines a collection
+    of resources as a single unit called a stack. AWS CloudFormation
+    creates and deletes all member resources of the stack together and
+    manages all dependencies between the resources for you.
+
+    For more information about this product, go to the `CloudFormation
+    Product Page`_.
+
+    Amazon CloudFormation makes use of other AWS products. If you need
+    additional technical information about a specific AWS product, you
+    can find the product's technical documentation at
