+//! Network Protocol
+//!
+//! a I/O-Free protocol for the veloren network crate.
+//! This crate defines multiple different protocols over [`UnreliableDrain`] and
+//! [`UnreliableSink`] traits, which allows it to define the behavior of a
+//! protocol separated from the actual io.
+//!
+//! For example we define the TCP protocol on top of Drains and Sinks that can
+//! send chunks of bytes. You can now implement your own Drain And Sink that
+//! sends the data via tokio's or std's implementation. Or you just use a
+//! std::mpsc::channel for unit tests without needing a actual tcp socket.
+//!
+//! This crate currently defines:
+//!  - TCP
+//!  - MPSC
+//!
+//! a UDP implementation will quickly follow, and it's also possible to abstract
+//! over QUIC.
+//!
+//! warning: don't mix protocol, using the TCP variant for actual UDP socket
+//! will result in dropped data  using UDP with a TCP socket will be a waste of
+//! resources.
+//!
+//! A *channel* in this crate is defined as a combination of *read* and *write*
+//! protocol.
+//!
+//! # adding a protocol
+//!
+//! We start by defining our DataFormat. For most this is prob [`Vec<u8>`] or
+//! [`Bytes`]. MPSC can directly send a msg without serialisation.
+//!
+//! Create 2 structs, one for the receiving and sending end. Based on a generic
+//! Drain/Sink with your required DataFormat.
+//! Implement the [`SendProtocol`] and [`RecvProtocol`] traits respectively.
+//!
+//! Implement the Handshake: [`InitProtocol`], alternatively you can also
+//! implement `ReliableDrain` and `ReliableSink`, by this, you use the default
+//! Handshake.
+//!
+//! This crate also contains consts and definitions for the network protocol.
+//!
+//! For an *example* see `TcpDrain` and `TcpSink` in the [tcp.rs](tcp.rs)
