-== Introduction to Part Two
+== Lightning Network Architecture
 
 In the first part of this book we introduced the main concepts of the Lightning Network, worked through a comprehensive example of routing a payment and set up the tools we can use to explore further. In the second part of the book we will explore the Lightning Network in a lot more technical detail, dissecting each of the building blocks.

 == Routing on a Network of Payment channels
 
-In this section we will finally unpack how payment channels can be connected to a network of other payment channels via a process called _routing_. Specifically, we will look at the first part of the routing layer, the Atomic & Trustless Multihop Payment protocol. This is highlighted by a double outline in the protocol suite diagram:
