+## Using Docker
+
+This template includes a `Dockerfile` and `.dockerignore` for easy containerization.
+
+### Build and Run with Docker
+
+1. **Build the Docker image:**
+   ```sh
+   docker build -t my-app .
+   ```
+2. **Run the container:**
+
+   ```sh
+   # Interactive mode (for development/debugging)
+   docker run -it --rm -p 3000:3000 my-app
+
+   # Detached mode (for background/production use)
+   docker run -d --rm -p 3000:3000 my-app
+   ```
+
+You can customize the `Dockerfile` to fit your stack (Node.js, React, etc.).
+
+Refer to the `Dockerfile` for details and adjust exposed ports or environment variables as needed.
