+## Keep README.hu.md maintained
+
+This repo ships a Hungarian translation, `README.hu.md`, alongside
+`README.md`. Whenever a change touches `README.md`, update
+`README.hu.md` in the same PR — don't let it drift out of sync.
+
+Translate for a native Hungarian technical reader, not word-for-word.
+Prefer the phrasing and terminology a Hungarian engineer would actually
+use over a literal, mechanical translation — no cheap/robotic-sounding
+translations. Code blocks, file paths, flag names, environment
+variables, and other literal identifiers stay unchanged, exactly as in
+the existing `README.hu.md`.
