+
+````
+make CONFIG_PLATFORM_ARM_SUNXI=y ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -C /path/to/kernel_compile_O_dir M=$PWD CONFIG_RTL8723BS=m -j$(nproc)

+To compile for the host, do something like this:
+
+```
+sudo apt-get install build-essential linux-headers-generic git
+git clone https://github.com/muhviehstah/rtl8723bs.git
+cd rtl8723bs
+make
