 The modernization includes:
 * Ethernet 2.0 library functions
+* compatible include file names EthernetClient.h, EthernetServer.h and EthernetUdp.h 
 * support of many Arduino architectures by using the SPI library
 * SPI transactions to share the SPI bus with devices with different communication settings
 * SPI communication at 20 MHz if the MCU supports it, else on the maximum supported by the MCU
 * client.flush() to send the packet immediately

-This library doesn't have examples, because examples of the Arduino Ethernet library apply. You can find them in the Arduino IDE Examples menu Ethernet section. Only change `#include <Ethernet.h>` to `#include <EthernetENC.h>`.  
+Limitations:
+* UDP.beginMulticast is not supported, because the uIP stack doesn't support multicast
+* UDB broadcasts receiving is turned off on ENC to lower the processing load on the library
+* EthernetServer doesn't support the print-to-all-clients functionality, because it takes flash memory space and RAM (10 bytes) and nobody uses it
 
-This library is based on the Norbert Truchsess's arduino-uip original source code repository and uses experience from the development of the multiarchitecture support by Cassy for UIPEthernet library which is published in Library Manager. Applicable fixes and enhancements from developed of EthernetENC were transfered to Cassy's UIPEthernet.
