A few things are stale or missing:
- Using the term 'kernel' is outdated at this point. It's been years
since Zephyr was just a kernel, and we now include many modules as
well as our internal subsystems and driver layers. Make that clearer
in the overview.
- Devicetree overlays are a basic piece of zephyr applications and
they're worth highlighting at this introductory place as well. Note
that neither app.overlay or prj.conf are actually required to be
present, so if we're mentioning prj.conf here, we might as well
mention app.overlay too.
- Explain the basic purpose of and differences between Kconfig
fragments and DT overlays.
Clean up some other language and provide some more cross references.
