pi4 uart setup

Dear all , just got my new pi4 , i can see it has uart Tx on GPIO 12 and uart Rx on GPIO 13. In order to use this as a serial port , gpio needs to be in ALT4 Mode , new /dev/ttyS5 device needs to be created and device file needs to be mapped to these pins. Can any one help me do that. Thank You Sach...
