History

Martí Bolívar a6b86446d4 doc: hello_world: touch up README Since this is such a basic sample, it's worth nitpicking the wording a bit: - Add a link to the supported boards, since many first time users will not know where it is and may start near here. - Remove the single and multi threaded note. There's no information on how to build it in either of these two modes or what the default is, so it feels like a distraction for such a basic sample. - Give a clue about how to build for another board.

A simple sample that can be used with any :ref:`supported board <boards>` and
prints "Hello World" to the console.

Building and Running
********************

This application can be built and executed on QEMU as follows:

   :zephyr-app: samples/hello_world
   :host-os: unix
   :board: qemu_x86
   :goals: run
   :compact:

To build for another board, change "qemu_x86" above to that board's name.
