# Clone this repository
$ git clone https://github.com/Gojikovi/kernel_samsung_universal9611

# Go into the repository

# Install toolchain
# You could try any clang/LLVM based toolchain, however I use WeebX clang
# See the intructions: https://github.com/XSans0/WeebX-Clang

# Building kernel is simple, a python script is provided.
# Options inside parenthesis are optional, Parenthesis' with | between 
# means you have to provide one of those options inside.
$ python build_kernel.py (--aosp|--oneui) --target=m31 (--no-ksu) (--allow-dirty)

After build the image of the kernel will be in out/arch/arm64/boot/Image

How To Flash
