The engine exposes only SMBus BYTE_DATA/WORD_DATA, so i2cdetect (which needs SMBus QUICK or READ_BYTE) cannot scan the bus. Replace the misleading "i2cdetect -r/-y" scan instructions with a direct i2cget byte-data read in the README, the cover letter and the smoke test. Also gitignore the archived internal working documents (docs/archive-*.md). Signed-off-by: Simone Chifari <simone.chifari@gmail.com>
