+## Run with Docker
+
+You can also run this project using Docker.
+
+### Using Docker Compose (Recommended)
+
+To start the application and its dependencies (like the database and attachment storage):
+
+```bash
+docker-compose up -d --build
+```
+
+The application will be accessible at `http://localhost:3000`. Persistent data (the database and attachments) will be stored in the local directory.
+
+### Using Docker Directly
+
+1. Build the image:
+   ```bash
+   docker build -t blog-cms .
+   ```
+
+2. Run the container:
+   ```bash
+   docker run -d \
+     -p 3000:3000 \
+     -v $(pwd)/data.db:/app/data.db \
+     -v $(pwd)/attachments:/app/attachments \
+     --name blog-cms \
+     blog-cms
+   ```
