+## Installation and Setup with Docker
+
+1. Clone the repository:
+   ```
+   git clone https://github.com/yourusername/url-manager.git
+   cd url-manager
+   ```
+
+2. Build the Docker image:
+   ```
+   docker build -t url-manager .
+   ```
+
+3. Create a Docker volume for persistent database storage:
+   ```
+   docker volume create url-manager-data
+   ```
+
+4. Run the Docker container:
+   ```
+   docker run -d --name url-manager-container -p 8000:8000 -v url-manager-data:/app/data url-manager
+   ```
+
+5. Initialize the database and create a superuser:
+   ```
+   docker exec -it url-manager-container python manage.py migrate
+   docker exec -it url-manager-container python manage.py createsuperuser
+   ```
+
+6. Open your web browser and navigate to `http://localhost:8000` to access the application.
+
+## Usage
+
+- To create a new short URL, click on the "Create New Link" button on the home page.
+- To edit or delete a link, use the corresponding buttons in the link list.
+- To view detailed statistics for a link, click on the "Details" button.
+- Use the search bar in the navigation to quickly find links by alias or original URL.
+
+## Admin Interface
+
+To access the admin interface:
+
+1. Go to `http://localhost:8000/admin`
+2. Log in with the superuser account you created earlier
+
+## Changing the Language
+
+To switch between English and Simplified Chinese, use the language selector in the navigation bar.
+
+## Persistent Data
+
+The SQLite database is stored in the Docker volume `url-manager-data`. This ensures that your data persists even if the container is stopped or removed. To backup your data, you can copy the contents of this volume.
