        * Mount the image in /mnt/rpi directory.

        .. code-block:: c

                $ sudo mkdir /mnt/rpi
                $ sudo mount -o loop,offset=4194304 2023-12-05-raspios-bullseye-arm64.img /mnt/rpi

        * Create a file name ssh to enable ssh.

        .. code-block:: c

                $ cd /mnt/rpi
                $ sudo touch ssh


        * Create a userconf.txt to store the credentials.

        .. code-block :: c

                $ sudo touch userconf.txt

        * Create the username and password the OS using openssl command.

        .. code-block:: c

                test:~$ openssl passwd -6

        * add the credentials in the userconf.txt

        .. code-block:: c

        * go to the directory qemu_rpi_3b and umount the image.

        .. code-block:: c

                $ cd $HOME/qemu_rpi_3b
                $ sudo umount /mnt/rpi
