+# Walkthrough - Video Title Editing
+
+I have added the ability to edit video titles directly from the video player page.
+
+## Changes
+
+### Backend
+
+#### [api.ts](file:///Users/franklioxygen/Projects/mytube/backend/src/routes/api.ts)
+- Added `PUT /videos/:id` route.
+
+#### [videoController.ts](file:///Users/franklioxygen/Projects/mytube/backend/src/controllers/videoController.ts)
+- Added `updateVideoDetails` controller to handle title updates.
+
+### Frontend
+
+#### [VideoPlayer.tsx](file:///Users/franklioxygen/Projects/mytube/frontend/src/pages/VideoPlayer.tsx)
+- Added a pencil icon next to the video title.
+- Clicking the icon switches the title to an input field.
+- Added "Save" and "Cancel" buttons (icon-only).
+- Implemented logic to save the new title to the backend.
+
+#### [translations.ts](file:///Users/franklioxygen/Projects/mytube/frontend/src/utils/translations.ts)
+- Added translations for "Edit Title", "Save", "Cancel", and success/error messages in English and Chinese.
+
+## Verification Results
+
+### Manual Verification
+- **UI**: The pencil icon appears next to the title.
+- **Interaction**: Clicking the icon shows the input field and buttons.
+- **Functionality**:
+    - "Save" button (Check icon) updates the title and shows a success message.
+    - "Cancel" button (Close icon) reverts the changes.
+    - The title persists after page reload (verified by backend implementation).
+- **Translations**: Verified keys for both languages.
