+# MediaCMS Chapters Editor
+
+A modern browser-based chapter editing tool built with React and TypeScript that integrates with MediaCMS. The Chapters Editor allows users to create, manage, and edit video chapters with precise timing controls and an intuitive timeline interface.
+
+## Features
+
+- 📑 Create and manage video chapters with custom titles
+- ⏱️ Precise timestamp controls for chapter start and end points
+- ✂️ Split chapters and reorganize content
+- 👁️ Preview chapters with jump-to navigation
+- 🔄 Undo/redo support for all editing operations
+- 🏷️ Chapter metadata editing (titles, descriptions)
+- 💾 Save chapter data directly to MediaCMS
+- 🎯 Timeline-based chapter visualization
+- 📱 Responsive design for desktop and mobile
+
+## Use Cases
+
+- **Educational Content**: Add chapters to lectures and tutorials for better navigation
+- **Entertainment**: Create chapters for movies, shows, or long-form content
+- **Documentation**: Organize training videos and documentation with logical sections
+- **Accessibility**: Improve content accessibility with structured navigation
+
+## Tech Stack
+
+- React 18
+- TypeScript
+- Vite
+
+## Installation
+
+### Prerequisites
+
+- Node.js (v20+) - Use `nvm use 20` if you have nvm installed
+- Yarn or npm package manager
+
+### Setup
+
+```bash
+# Navigate to the Chapters Editor directory
+cd frontend-tools/chapters-editor
+
+# Install dependencies with Yarn
+yarn install
+
+# Or with npm
+npm install
+```
+
+## Development
+
+The Chapters Editor can be run in two modes:
+
+### Standalone Development Mode
+
+This starts a local development server with hot reloading:
+
+```bash
+# Start the development server with Yarn
+yarn dev
+
+# Or with npm
+npm run dev
+```
+
+### Frontend-only Development Mode
+
+If you want to work only on the frontend with MediaCMS backend:
+
+```bash
+# Start frontend-only development with Yarn
+yarn dev:frontend
+
+# Or with npm
+npm run dev:frontend
+```
+
+## Building
+
+### For MediaCMS Integration
+
+To build the Chapters Editor for integration with MediaCMS:
+
+```bash
+# Build for Django integration with Yarn
+yarn build:django
+
+# Or with npm
+npm run build:django
+```
+
+This will compile the editor and place the output in the MediaCMS static directory.
+
+### Standalone Build
+
+To build the editor as a standalone application:
+
+```bash
+# Build for production with Yarn
+yarn build
+
+# Or with npm
+npm run build
+```
+
+## Deployment
+
+To deploy the Chapters Editor, you can use the build and deploy script (recommended):
+
+```bash
+# Run the deployment script
+sh deploy/scripts/build_and_deploy.sh
+```
+
+The build script handles all necessary steps for compiling and deploying the editor to MediaCMS.
+
+You can also deploy manually after building:
+
+```bash
+# With Yarn
+yarn deploy
+
+# Or with npm
+npm run deploy
+```
+
+## Project Structure
+
+- `/client` - Frontend React application
+    - `/src` - Source code
+        - `/components` - React components for chapter editing
+        - `/hooks` - Custom React hooks for chapter management
+        - `/lib` - Utility functions and helpers
+        - `/services` - API services for MediaCMS integration
+        - `/styles` - CSS and style definitions
+- `/shared` - Shared TypeScript types and utilities
+
+## API Integration
+
+The Chapters Editor interfaces with MediaCMS through a set of API endpoints for:
+
+- Retrieving video metadata and existing chapters
+- Saving chapter data (timestamps, titles, descriptions)
+- Validating chapter structure and timing
+- Integration with MediaCMS user permissions
+
+### Chapter Data Format
+
+Chapters are stored in the following format:
+
+```json
+{
+    "chapters": [
+        {
+            "id": "chapter-1",
+            "title": "Introduction",
+            "startTime": 0,
+            "endTime": 120,
+            "description": "Opening remarks and overview"
+        },
+        {
+            "id": "chapter-2",
+            "title": "Main Content",
+            "startTime": 120,
+            "endTime": 600,
+            "description": "Core educational material"
+        }
+    ]
+}
+```
+
+## Code Formatting
+
+To automatically format all source files using [Prettier](https://prettier.io):
+
+```bash
+# Format all code in the src directory
+npx prettier --write client/src/
+
+# Or format specific file types
+npx prettier --write "client/src/**/*.{js,jsx,ts,tsx,json,css,scss,md}"
+```
+
+You can also add this as a script in `package.json`:
+
+```json
+"scripts": {
+  "format": "prettier --write client/src/"
+}
+```
+
+Then run:
+
+```bash
+yarn format
+# or
+npm run format
+```
+
+## Testing
+
+Run the test suite to ensure Chapters Editor functionality:
+
+```bash
+# Run tests with Yarn
+yarn test
+
+# Or with npm
+npm test
+
+# Run tests in watch mode
+yarn test:watch
+npm run test:watch
+```

+
+## Troubleshooting
+
+### Common Issues
+
+**Chapter timestamps not saving**: Ensure the MediaCMS backend API is accessible and user has proper permissions.
+
+**Timeline not displaying correctly**: Check browser console for JavaScript errors and ensure video file is properly loaded.
+
+**Performance issues with long videos**: The editor is optimized for videos up to 2 hours. For longer content, consider splitting into multiple files.
+
+### Debug Mode
+
+Enable debug mode for detailed logging:
+
+```bash
+# Start with debug logging
+DEBUG=true yarn dev
+```
