RC522 Write

I'm newbie with arduino and my english is not good
I find this code myarduino/RC522DumpMifare.ino at master · rena2019/myarduino · GitHub
Someone can explain me how can i use MFRC522_Write() implemented.
Thanks a lot.

selectCard, MFRC522_Auth, MFRC522_Write should work. Btw what is your native language?
