+# Deployment Guide for MyTube
+
+This guide explains how to deploy MyTube to a QNAP Container Station.
+
+## Prerequisites
+
+- Docker Hub account
+- QNAP NAS with Container Station installed
+- Docker installed on your development machine
+
+## Docker Images
+
+The application is containerized into two Docker images:
+
+1. Frontend: `franklioxygen/mytube:frontend-latest`
+2. Backend: `franklioxygen/mytube:backend-latest`
+
+## Deployment Process
+
+### 1. Build and Push Docker Images
+
+Use the provided script to build and push the Docker images to Docker Hub:
+
+```bash
+# Make the script executable
+chmod +x build-and-push.sh
+
+# Run the script
+./build-and-push.sh
+```
+
+The script will:
+
+- Build the backend and frontend Docker images optimized for amd64 architecture
+- Push the images to Docker Hub under your account (franklioxygen)
+
+### 2. Deploy on QNAP Container Station
+
+1. Copy the `docker-compose.yml` file to your QNAP NAS
+2. Open Container Station on your QNAP
+3. Navigate to the "Applications" tab
+4. Click on "Create" and select "Create from YAML"
+5. Upload the `docker-compose.yml` file or paste its contents
+6. Click "Create" to deploy the application
+
+#### Volume Paths on QNAP
+
+The docker-compose file is configured to use the following specific paths on your QNAP:
+
+```yaml
+volumes:
+  - /share/CACHEDEV2_DATA/Medias/MyTube/uploads:/app/uploads
+  - /share/CACHEDEV2_DATA/Medias/MyTube/data:/app/data
+```
+
+Ensure these directories exist on your QNAP before deployment. If they don't exist, create them:
+
+```bash
+mkdir -p /share/CACHEDEV2_DATA/Medias/MyTube/uploads
+mkdir -p /share/CACHEDEV2_DATA/Medias/MyTube/data
+```
+
+### 3. Access the Application
+
+Once deployed:
+
+- Frontend will be accessible at: http://192.168.1.105:5556
+- Backend API will be accessible at: http://192.168.1.105:5551/api
+
+## Volume Persistence
+
+The Docker Compose setup includes a volume mount for the backend to store downloaded videos:
+
+```yaml
+volumes:
+  backend-data:
+    driver: local
+```
+
+This ensures that your downloaded videos are persistent even if the container is restarted.
+
+## Network Configuration
+
+The services are connected through a dedicated bridge network called `mytube-network`.
+
+## Environment Variables
+
+The Docker images have been configured with the following default environment variables:
+
+### Frontend
+
+- `VITE_API_URL`: http://192.168.1.105:5551/api
+- `VITE_BACKEND_URL`: http://192.168.1.105:5551
+
+### Backend
+
+- `PORT`: 5551
+
+## Troubleshooting
+
+If you encounter issues:
+
+1. Check if the Docker images were successfully pushed to Docker Hub
+2. Verify that Container Station has internet access to pull the images
+3. Check Container Station logs for any deployment errors
+4. Ensure ports 5551 and 5556 are not being used by other services on your QNAP
+5. If backend fails with Python-related errors, verify that the container has Python installed

+# MyTube
+
+A YouTube/Bilibili video downloader and player application that allows you to download and save YouTube/Bilibili videos locally, along with their thumbnails. Organize your videos into collections for easy access and management.
+
+## Features
+
+- Download YouTube videos with a simple URL input
+- Automatically save video thumbnails
+- Browse and play downloaded videos
+- View videos by specific authors
+- Organize videos into collections
+- Add or remove videos from collections
+- Responsive design that works on all devices
+
+## Directory Structure
+
+```
+mytube/
+├── backend/             # Express.js backend
+│   ├── uploads/         # Uploaded files directory
+│   │   ├── videos/      # Downloaded videos
+│   │   └── images/      # Downloaded thumbnails
+│   └── server.js        # Main server file

+├── start.bat            # Windows startup script
+└── package.json         # Root package.json for running both apps
+```
+
+## Getting Started
+
+### Prerequisites
+
+- Node.js (v14 or higher)
+- npm (v6 or higher)
+
+### Installation
+
+1. Clone the repository:
+
+   ```
+   git clone <repository-url>
+   cd mytube
+   ```
+
+2. Install dependencies:
+
+   ```
+   npm run install:all
+   ```
+
+   This will install dependencies for the root project, frontend, and backend.
+
+#### Using npm Scripts
+
+Alternatively, you can use npm scripts:
+
+```
+npm run dev       # Start both frontend and backend in development mode
+```
+
+Other available scripts:
+
+```
+npm run start     # Start both frontend and backend in production mode
+npm run build     # Build the frontend for production
+```
+
+### Accessing the Application
+
+- Frontend: http://localhost:5556
+- Backend API: http://localhost:5551
+
+## API Endpoints
+
+- `POST /api/download` - Download a YouTube video
+- `GET /api/videos` - Get all downloaded videos
+- `GET /api/videos/:id` - Get a specific video
+- `DELETE /api/videos/:id` - Delete a video
+
+## Collections Feature
+
+MyTube allows you to organize your videos into collections:
+
+- **Create Collections**: Create custom collections to categorize your videos
+- **Add to Collections**: Add videos to collections directly from the video player
+- **Remove from Collections**: Remove videos from collections with a single click
+- **Browse Collections**: View all your collections in the sidebar and browse videos by collection
+- **Note**: A video can only belong to one collection at a time
+
+## User Interface
+
+The application features a modern, dark-themed UI with:
+
+- Responsive design that works on desktop and mobile devices
+- Video grid layout for easy browsing
+- Video player with collection management
+- Author and collection filtering
+- Search functionality for finding videos
+
+## Environment Variables
+
+The application uses environment variables for configuration. Here's how to set them up:
+
+### Frontend (.env file in frontend directory)
+
+```
+VITE_API_URL=http://{host}:{backend_port}/api
+VITE_BACKEND_URL=http://{host}:{backend_port}
+```
+
+### Backend (.env file in backend directory)
+
+```
+PORT={backend_port}
+```
+
+Copy the `.env.example` files in both frontend and backend directories to create your own `.env` files and replace the placeholders with your desired values.

+# React + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react/README.md) uses [Babel](https://babeljs.io/) for Fast Refresh
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend using TypeScript and enable type-aware lint rules. Check out the [TS template](https://github.com/vitejs/vite/tree/main/packages/create-vite/template-react-ts) to integrate TypeScript and [`typescript-eslint`](https://typescript-eslint.io) in your project.
