Configure Zephyr: Kconfigs and Devicetree in Simple Words
summary
Explains exactly how Kconfig and Devicetree become usable artifacts: board _defconfig + project.conf + fragments merge into .config and generate autoconf.h, while board DTS plus app overlays merge into zephyr.dts and produce generated headers; uses menuconfig / guiconfig for safe edits, shows making persistent fragments via set(EXTRA_CONF_FILE) or saving a minimal config and diffing, demonstrates enabling Tracealyzer with ring‑buffer settings, notes common pinmux/IRQ issues and debugging by reading the first build error and the DTSI include chain.
