-.. rubric:: Everything about cloud-init, a set of **python** scripts and
-            utilities to make your cloud images be all they can be!
+Cloud-init is the *industry standard* multi-distribution method for
+cross-platform cloud instance initialization. It is supported across all
+major public cloud providers, provisioning systems for private cloud
+infrastructure, and bare-metal installations.
 
-*******
-Summary
-*******
+Cloud instances are initialized from a disk image and instance data:
 
-`Cloud-init`_ is the *defacto* multi-distribution package that handles early
-initialization of a cloud instance.
+- Cloud metadata
+- User data (optional)
+- Vendor data (optional)
 
-----
+Cloud-init will identify the cloud it is running on during boot, read any
+provided metadata from the cloud and initialize the system accordingly. This
+may involve setting up the network and storage devices to configuring SSH
+access key and many other aspects of a system. Later on the cloud-init will
+also parse and any optional user or vendor data that was passed to the
+instance.
