-As the Lightning Network is a peer-to-peer network, some initial bootstrapping is required in order for peers to discover each other.  Within this chapter we'll follow the story of a new peer connecting to the network for the first time, and examine each step in the bootstrapping process from initial peer discovery, to channel graph syncing and validation.
+As the Lightning Network is a peer-to-peer network, some initial bootstrapping is required in order for peers to discover each other.  Within this chapter we'll follow the story of a new peer connecting to the network for the first time, and examine each step in the bootstrapping process from initial peer discovery to channel graph syncing and validation.
 
 As an initial step, our new node needs to somehow _discover_ at least _one_ peer that is already connected to the network and has a full channel graph (as we'll see later, there's no canonical version of the channel graph). Using one of many initial bootstrapping protocols to find that first peer, after a connection is established, our new
 peer now needs to _download_ and _validate_ the channel graph. Once the channel graph has been fully validated, our new peer is ready to start opening channels and sending payments on the network.
