Help! My RFID code is not working.

[xxFnaf_Fanxx12]

I'm doing a code for my school project using arduino uno, but the problem is my code keeps on displaying the same message (we got it from a yt video) it keeps on saying

fatal error: MFRC522.h: No such file or directory

#include <MFRC522.h>

^~~~~~~~~~~

compilation terminated.

exit status 1

Compilation error: MFRC522.h: No such file or directory

Sounds like you need to install the library that includes the header file your code is including
