# Manual test procedure: get Zephyr Kernel, build an example, and run in Qemu:
#
# $ wget https://github.com/zephyrproject-rtos/zephyr/archive/master.tar.gz
# $ tar xf master.tar.gz
# $ cd zephyr-master
# $ source zephyr-env.sh
# $ cd samples/hello_world
# $ mkdir build && cd build
# $ cmake -GNinja -DBOARD=qemu_x86..
# $ ninja run

# Alternative using West:
#
# $ west init testws
# $ cd testws
# $ west update
# $ cd zephyr
# $ west build --pristine=always -b qemu_x86 samples/hello_world
# $ cd build
# $ ninja run
