 ## Architecture
 Fabric is two things — a protocol for machines to exchange information ("the Fabric Protocol"), and a sotware library (`@fabric/core`) offering up many tools and utilities for building your own networks which speak this protocol.
 
+Typically, you will need the following:

 ### Overview
 Using Fabric to interface securely with decentralized systems, you'll start by following the instructions above to obtain a globally-available version of the `fabric` command-line client, which provides the majority of tools you'll need along the way.

+## What is Fabric?
+`@fabric/core` provides the reference implementation for [the Fabric Protocol][protocol], a "language" for exchanging information through peer-to-peer networks.  Written in JavaScript, it is meant to be well-documented and easy to understand — but not the final implementation.
