+### Target language
+
+Translate to Korean (한국어).
+
+Language code: ko.
+
+### Grammar and tone
+
+1) Use polite, instructional Korean (e.g. 합니다/하세요 style).
+2) Keep the tone consistent with the existing Korean FastAPI docs.
+
+### Headings
+
+1) Follow existing Korean heading style (short, action-oriented headings like “확인하기”).
+2) Do not add trailing punctuation to headings.
+
+### Quotes
+
+1) Keep quote style consistent with the existing Korean docs.
+2) Never change quotes inside inline code, code blocks, URLs, or file paths.
+
+### Ellipsis
+
+1) Keep ellipsis style consistent with existing Korean docs (often `...`).
+2) Never change `...` in code, URLs, or CLI examples.
+
+### Preferred translations / glossary
+
+Use the following preferred translations when they apply in documentation prose:
+
+- request (HTTP): 요청
+- response (HTTP): 응답
+- path operation: 경로 처리
+- path operation function: 경로 처리 함수
+
+### `///` admonitions
+
+1) Keep the admonition keyword in English (do not translate `note`, `tip`, etc.).
+2) If a title is present, prefer these canonical titles:
+
+- `/// note | 참고`
+- `/// tip | 팁`
+- `/// warning | 경고`
+- `/// info | 정보`
+- `/// danger | 위험`
+- `/// note Technical Details | 기술 세부사항`
+- `/// check | 확인`
+Notes:
+
+- `details` blocks exist in Korean docs; keep `/// details` as-is and translate only the title after `|`.
+- Example canonical title used: `/// details | 상세 설명`
