 For example, to compile the command-line tools for `arm64`, you can run:
 
 ```bash
-make all ARCH=arm64 LOG=LOG_WARN KDIR=~/linux
+make all ARCH=arm64 LOG=LOG_WARNING KDIR=~/linux

 This will generate the tools in `tools/hvisor` and the kernel module in `driver/hvisor.ko`, which you can copy to the root Linux root filesystem and use.
