+Make kernel.
+
+Options:
+  -h, --help                 Print this help message
+  -k, --kerneldir DIR        Location of the kernel sources
+  -c, --kernel-config FILE   Kernel configuration file to use for compilation
+  -t, --make-tarball FILE    Make archive containing kernel,initramfs and modules.
+  -n, --kernel-name NAME     Tag the kernel and ramdisk with a name:
+                             If not defined the option defaults to
+                             'calculate'
+  -e, --extraversion VER     Specify extraversion for kernel
+  -v, --kernel-version VER   Specify version for kernel
+  -r, --remove-splash        Remove splash images from initramfs.
+  --no-clean                 Do not run make clean before compilation
+  --menuconfig               Run menuconfig after oldconfig
+
+Examples:
+
+The most common use is to run it like this, which build and install current kernel.
