-# Library for E1.31 sACN
-## `Lightweight streaming protocol for transport of DMX512 using ACN`
-
-## Top level include
-
-Include `sacn.h` for full protocol support.
-
-> ```#include "sacn.h"```
-
-### Requirements
-Expects to also have the `acn` and `dmx` libraries in the include path.
-
-## Logical components
-
-### Protocol Handling
-* `sacn.h`: [`SACN`] protocol constants.
-* `data.h`: [`SACN::DATA`] protocol support for `VECTOR_ROOT_E131_DATA` packets.
-* `extended.h`: [`SACN::EXTENDED`] protocol support for `VECTOR_ROOT_E131_EXTENDED` packets
-
-### Data Classes
-* `universe.h`: [`SACN::Universe`]  A set of up to 512 data slots identified by universe number. Note: In E1.31 there may be multiple sources for a universe.
-> For protocol agnostic universe refer to the base class, `DMX::Universe`
-
-* `receiver.h`: [`SACN::Receiver`] A receiver is the intended target of information from a source. A receiver may listen for multiple universes.
-
-* `source.h`: [`SACN::Source`] A sACN component that assembles, formats, and transmits data to one or many receivers.
-
-* `node.h`: [`SACN::Node`] A class that inherits from both `SACN::Source` and `SACN::Receiver`.  IE. can both send and receive.  The node class also manages universe discovery.
-
-### Reference Implementations
-
-Several reference implementations may be available in the `platform` subdirectory.
-
-* `receiver-esp.h`: [`SACN::EspReceiver`] A reference implementation, derived from `SACN::Receiver` for use with ESP devices and Arduino.
-
-* `qsacnnode.h`: [`SACN::QSacnNode`] An implementation that inherits from `SACN::Node`, which handles all of the mucky hardware and network with Qt.
-
-## Usage with Arduino
-
-Include `receiver-esp.h` at the top of your sketch.
-
-Create a receiver object.
-> ```
-> EspReceiver * e131 = new EspReceiver();
-> ```
-
-In `setup`, subscribe to a universe an register a callback for data activity.
-> ```
-setup() {
-  e131->subscribe(1);
-  e131->universe(1)->onData(std::bind(&universeHandler,
-                                      std::placeholders::_1));
-}
->```
-
-Write a handler function with the follow signature (returns `void`, requires 1 argument, a `Universe` pointer):
-> ```
-void universeHandler(Universe * universe) {
-  do something...
-}
-> ```
