 ## Building
-Documented later :)
+- Step 1: Get the toolchain by `git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9 && cd aarch64-linux-android-4.9 && git checkout ndk-release-r19`. Also install `bc` if you don't have it yet. On Debian-based distributions use `sudo apt install bc`, on Redhat-based use `sudo rpm install bc`
+- Step 2: Clone this repo by `git clone https://github.com/raspiduino/sm-a600g-kvm`
+- Step 3: Change the directory back to the kernel source by `cd ../sm-a600g-kvm`
+- Step 4: Setup environment variable `export CROSS_COMPILE=../aarch64-linux-android-4.9/bin/aarch64-linux-android- ANDROID_MAJOR_VERSION=p ARCH=arm64`
+- Step 5: Make menuconfig by `make exynos7870-a6lte_defconfig && make menuconfig`
+- Step 6: Goto `Boot options` and then turn off all options which has `TIMA` and `RKP`. Then click exit to go back to main menu. Enable `Virtualization` by pressing the space key. Goto `Virtualization` menu and enable `Kernel-based Virtual Machine (KVM) support`. After that, exit menuconfig and save `.config` file.
+- Step 7: Run `make Image -j8` to build. You can replace `-j8` by `-j[NUMBER OF THREAD TO RUN]`
+- Step 8: Enjoy your kernel! Details about flashing it will be here later :)
