+# Running the Project with Docker
+
+This section provides instructions to build and run the project using Docker.
+
+## Requirements
+
+- Docker version 20.10 or later
+- Docker Compose version 1.29 or later
+
+## Environment Variables
+
+- `POSTGRES_USER`: Database username (default: `user`)
+- `POSTGRES_PASSWORD`: Database password (default: `password`)
+- `POSTGRES_DB`: Database name (default: `appdb`)
+
+## Build and Run Instructions
+
+1. Clone the repository and navigate to the project root directory.
+2. Build and start the services using Docker Compose:
+   ```bash
+   docker-compose up --build
+   ```
+3. Access the application at `http://localhost:8080`.
+
+## Configuration
+
+- The application binary is built using Go version 1.24.
+- The database service uses the `postgres:latest` image.
+
+## Exposed Ports
+
+- Application: `8080` (mapped to `8080` on the host)
+- Database: Not exposed to the host
+
+For further details, refer to the project documentation or contact the maintainers.
