-# 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.
