 # X-NUCLEO-NFC05A1
-Arduino library to support NFC card reader expansion board based on ST25R3911B
+
+The code has been designed for ST X-NUCLEO-NFC05A1 expansion board to show how to detect, read and write NFC tags.
+The X-NUCLEO-NFC05A1 is an NFC card reader evaluation board based on ST25R3911B to enable expansion of the STM32 Nucleo boards.
+The ST25R3911B manages frame coding and decoding in Reader mode for standard applications, such as NFC, proximity and vicinity HF RFID standards.
+The ST25R3911B supports ISO/IEC 14443 Type A and B, ISO/IEC 15693 (single Subcarrier only) and ISO/IEC 18092 communication protocols. 
+It also supports the detection, reading and writing of NFC Forum Type 1, 2, 3, 4 and 5 tags.
+
+## Examples
+
+There is one example with the X-NUCLEO-NFC05A1 library: 
+* X_NUCLEO_NFC05A1_HelloWorld: This application is to show how to detect, read and write NFC Forum Type 1, 2, 3, 4 and 5 tags.
+  Open a serial terminal with a baudrate of 115200, 8 data bits, No parity bit, 1 stop bit and follow the instructions shown by the menu.
+  Pushing the User Button, you can switch to several options like writing a text record, writing a URI record and an Android Application record, 
+  formatting an ST tag or reading the content of a tag.  
+
