 # Introduction
 
-The Peering API will be developed as a methodology for removing obstacles for connecting people.  By automating interconnections, any network which implements the API will automatically be able to peer with any network in public or private scenarios in a time faster than it would take to configure sessions manually.  By speeding up peering and removing the need to get another person involved in peering, the API and automation will ensure that networks can get as interconnected as possible, as fast as possible.  This improves end-user performance for all applications using networks supporting the peering API.  
+The Peering API will be developed as a methodology to remove obstacles for interdomain interconnection through global Internet Routing.  
+By automating interconnections between Autonomous Systems, any network which implements the API will automatically be able to peer with any network participating in public or private scenarios in a time faster than it would take to configure sessions manually.  
+The proposed API and automation will ensure that networks can get as interconnected as possible, as fast as possible, with as little manual work as possible.

 Business Justification:
 1.  Reduction in person-hours spent configuring peering
