Walkthrough

Replaces USBImager with Armbian Imager as the recommended SD‑card flashing tool throughout docs/User-Guide_Getting-Started.md. Adds an Armbian Imager workflow visualization and step‑by‑step instructions for downloading and/or flashing images, lists Armbian Imager capabilities (select/download official images, flash .img/.img.xz and custom images, verify writes, protect targets), and generalizes warnings about safe target selection and verification. Removes prior tool-specific recommendations, explicitly notes balenaEtcher is not recommended due to decompression-related issues, and updates guidance to be tool‑agnostic while preferring Armbian Imager.

8-12: Tool migration successfully completed; introduction now consistent with deployment sections.

The introduction properly establishes Armbian Imager as the recommended tool with workflow visualization and clear capability description. This now aligns consistently with the updated "Download the image" and "Flash to SD Card" sections.

---

185-207: Flash to SD Card section successfully updated to feature Armbian Imager as the primary tool.

The section now provides clear step-by-step instructions (lines 194–199), enumerates Armbian Imager's capabilities (lines 187–192), and the warning section (lines 201–207) appropriately emphasizes verification and safe target selection while recommending Armbian Imager and noting balenaEtcher's decompression issues. The migration from USBImager is complete and coherent throughout this section.
