 This is simple yet complete WebServer library for `STM32` boards running built-in Ethernet (Nucleo-144, Discovery) or EMC28J60 Ethernet shields. The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32.

 3. HTTP Server and Client
 4. HTTP GET and POST requests, provides argument parsing, handles one client at a time.
 
 ## TO DO
 1. Bug Searching and Killing
 2. Add SSL/TLS Client and Server support
-3. Support more types of boards using Ethernet shields.
+3. Support more types of Ethernet shields such as W5x00, etc.
