 #### Features
 
 This [**WebServer_WT32_ETH01 library**](https://github.com/khoih-prog/WebServer_WT32_ETH01) is a simple yet complete WebServer wrapper library for **ESP32-based WT32_ETH01** boards using LAN8720 Ethernet. The functions are similar and compatible to those of [`ESP32 WebServer`](https://github.com/espressif/arduino-esp32/tree/master/libraries/WebServer) and [`ESP8266WebServer`](https://github.com/esp8266/Arduino/tree/master/libraries/ESP8266WebServer) libraries to make life much easier to port sketches from ESP8266/ESP32.
