-# ethwire
-
-The ethwire package contains the ethereum wire protocol. The ethwire
-package is required to write and read from the ethereum network.
-
-# Installation
-
-`go get github.com/ethereum/ethwire-go`
-
-# Messaging overview
-
-The Ethereum Wire protocol defines the communication between the nodes
-running Ethereum. Further reader reading can be done on the
-[Wiki](http://wiki.ethereum.org/index.php/Wire_Protocol).
-
-# Reading Messages
-
-```go
-// Read and validate the next eth message from the provided connection.
-// returns a error message with the details.
-msg, err := ethwire.ReadMessage(conn)
-if err != nil {
-  // Handle error
-}
-```
-
-# Writing Messages
-
-```go
-// Constructs a message which can be interpreted by the eth network.
-// Write the inventory to network
-err := ethwire.WriteMessage(conn, &Msg{
-  Type: ethwire.MsgInvTy,
-  Data : []interface{}{...},
-})
-```
