+# Running the Project with Docker
+
+This section provides instructions to build and run the project using Docker.
+
+## Prerequisites
+
+- Ensure Docker and Docker Compose are installed on your system.
+- The project requires Node.js version `22.13.1` as specified in the Dockerfile.
+
+## Environment Variables
+
+- If applicable, create a `.env` file in the project root directory to define environment variables. Uncomment the `env_file` line in the `docker-compose.yml` file to enable this.
+
+## Build and Run Instructions
+
+1. Build the Docker image and start the services:
+
+   ```bash
+   docker-compose up --build
+   ```
+
+2. Access the application at `http://localhost:8080`.
+
+## Configuration
+
+- The application runs with a non-root user for enhanced security.
+- The `NODE_ENV` is set to `production` and `NODE_OPTIONS` is configured for optimized memory usage.
+
+## Exposed Ports
+
+- The application service exposes port `8080` to the host system.
+
+For further details, refer to the provided `Dockerfile` and `docker-compose.yml` files.
