Linux Kernel makefile process explained

In LinuxSrc/Documentation/admin-guide/README.rst under the section for building the kernel exists these 4 steps, can someone explain what each one does? Is it similiar to a ./configure, ./make, ./install?

To configure and build the kernel, use:

1.) cd /usr/src/linux-4.X
2.) make O=/home/name/build/kernel menuconfig 
3.) make O=/home/name/build/kernel
4.) sudo make O=/home/name/build/kernel modules_install install

1) simple cd - no explanation needed

2) Running make menuconfig starts an ncurses-based text mode kernel configuration tool.

3) make O=/home/name/build/kernel configures and builds the kernel.

4.1) modules_install: This will copy the compiled modules into /lib/modules/-.

4.2) install: This command will copy following files into /boot directory (and might do more depending on the distribution): Config-, System.map-, Vmlinuz-*

vmlinuz - Is a compressed Linux kernel

system.map - Is a lookup table between symbol names and their addresses in memory for a particular build of a kernel

config - The kernel configuration created by the make menuconfig
