+## Translation Guidelines
+
+### 1. File Conversion Process
+- Current Korean docs → rename to `.ko.mdx` files
+- Create new English versions as default files (without locale suffix)
+- Maintain exact same file structure and organization
+
+### 2. Translation Rules
+- **Structure**: Never change document structure, headings hierarchy, or organization
+- **Code blocks**: Keep code exactly the same, only translate comments within code
+- **Frontmatter**: Translate all frontmatter fields (title, description, etc.)
+- **Content**: Translate all markdown content while preserving formatting
+
+### 3. Code Block Translation Example
+```typescript
+// Korean version (.ko.mdx)
+const map = new NaverMap({
+  center: { lat: 37.5665, lng: 126.9780 }, // 서울 중심좌표
+  zoom: 15 // 줌 레벨
+});
+
+// English version (default .mdx)
+const map = new NaverMap({
+  center: { lat: 37.5665, lng: 126.9780 }, // Seoul center coordinates
+  zoom: 15 // Zoom level
+});
+```
+
+### 4. Frontmatter Translation Example
+```yaml
+# Korean (.ko.mdx)
+---
+title: 카메라 컨트롤
+description: 네이버 맵의 카메라 움직임을 제어하는 방법
+---
+
+# English (default .mdx)
+---
+title: Camera Control
+description: How to control Naver Map camera movement
+---
+```
+
+### 5. Meta File Translation
+Meta files must also be localized for navigation menus and section titles:
+
+```json
+// English (meta.json)
+{
+  "title": "Documentation",
+  "icon": "Book",
+  "pages": [
+    "---Setup---",
+    "index",
+    "installation",
+    "---Usage---",
+    "components",
+    "---Guides---",
+    "marker-clustering",
+    "camera-control"
+  ]
+}
+
+// Korean (meta.ko.json)
+{
+  "title": "문서",
+  "icon": "Book", 
+  "pages": [
+    "---설정---",
+    "index",
+    "installation",
+    "---사용법---",
+    "components",
+    "---가이드---",
+    "marker-clustering",
+    "camera-control"
+  ]
+}
+```
+
+**Meta Translation Rules:**
+- Translate all text values (titles, section dividers)
+- Keep JSON structure, keys, and special formatting unchanged
+- Preserve external link formats like `[Icon][Text](URL)`
+- Don't translate proper nouns (Android, iOS, Expo)
