   .. tab-item:: Steps to Configure Kernel

        * The Linux kernel source code comes with the default configuration.

        * However, you can adjust it to your needs. To do so, follow the steps below:

        .. code-block:: c

                $ cd linux-6.0.7


        * Copy the existing Linux config file using the cp command:
        
        .. code-block:: c

                linux-6.0.7$ cp -v /boot/config-$(uname -r) .config
                "/boot/config-6.5.0-18-generic" -> ".config"

        * To make changes to the configuration file, run the make command:
        
        .. code-block:: c

                $ make menuconfig

        * The command launches several scripts that open the configuration menu:
        
        .. code-block:: c

                linux-6.0.7$ make menuconfig
