Read the kernel-build.sh source file and give the proper paths and stuff and change whatever you require. Recommended you copy the all files and folders except '.git' folder and README.md to you kernel source directory. After that cd to kernel directory and make the scipt executable.
$ chmod a+xr kernel-build.sh
$ ./kernel-build.sh
Note : Rememeber to give the proper paths to your directories otherwise the build script will exit (fail safe I included, can be removed).
Note : If your kernel requires other modules to be built then you will have to add the relevent code which takes care of that.
1.) kernel-build.sh : the build script uses bash.
2.) lazyflasher : this is the lazyflasher flashable zip file creation tool made by @jcadduono
3.) signzip : this is where the zip is signed automatically using the script.
4.) out : the newly signed flashable zip is placed here.
