.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: qemu_x86
   :goals: run
   :compact:

To build the single thread version, use the supplied configuration file for
single thread: :file:`prj_single.conf`:

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: qemu_x86
   :conf: prj_single.conf
   :goals: run
   :compact:
