+### Async TCP Library for ESP8266 Arduino
+
+For ESP32 look [https://github.com/ESP32Async/AsyncTCP](https://github.com/ESP32Async/AsyncTCP)
+
+This is a fully asynchronous TCP library, aimed at enabling trouble-free, multi-connection network environment for Espressif's ESP8266 MCUs.
+
+This library is the base for [https://github.com/ESP32Async/ESPAsyncWebServer](https://github.com/ESP32Async/ESPAsyncWebServer)
+
+## AsyncClient and AsyncServer
+The base classes on which everything else is built. They expose all possible scenarios, but are really raw and require more skills to use.
+
+## AsyncPrinter
+This class can be used to send data like any other ```Print``` interface (```Serial``` for example).
+The object then can be used outside of the Async callbacks (the loop) and receive asynchronously data using ```onData```. The object can be checked if the underlying ```AsyncClient```is connected, or hook to the ```onDisconnect``` callback.
+
+## AsyncTCPbuffer
+This class is really similar to the ```AsyncPrinter```, but it differs in the fact that it can buffer some of the incoming data.
+
+## SyncClient
+It is exactly what it sounds like. This is a standard, blocking TCP Client, similar to the one included in ```ESP8266WiFi```
