+# PostgreSQL Workflow Example
+
+This project demonstrates how to build and push a PostgreSQL Docker image using GitHub Actions. It includes a Dockerfile for creating the PostgreSQL image and a GitHub Actions workflow for automating the build and push process.
+
+## Project Structure
+
+```
+postgresql-workflow-example
+├── .github
+│   └── workflows
+│       └── postgres-image.yml  # GitHub Actions workflow for building and pushing the Docker image
+├── docker
+│   └── Dockerfile                # Dockerfile for PostgreSQL image
+├── src
+│   └── app.js                   # Main application file for connecting to the PostgreSQL database
+├── package.json                  # npm configuration file
+└── README.md                     # Project documentation
+```
+
+## Getting Started
+
+To get started with this project, follow these steps:
+
+1. **Clone the repository**:
+   ```bash
+   git clone <repository-url>
+   cd postgresql-workflow-example
+   ```
+
+2. **Build the Docker image**:
+   Navigate to the `docker` directory and build the image using the Dockerfile:
+   ```bash
+   cd docker
+   docker build -t your-postgres-image-name .
+   ```
+
+3. **Run the Docker container**:
+   After building the image, you can run it with:
+   ```bash
+   docker run --name your-container-name -e POSTGRES_PASSWORD=yourpassword -d your-postgres-image-name
+   ```
+
+## GitHub Actions Workflow
+
+The GitHub Actions workflow defined in `.github/workflows/postgres-image.yml` automates the process of building and pushing the Docker image to a container registry whenever changes are pushed to the main branch.
+
+## Usage
+
+You can connect to the PostgreSQL database using the credentials specified in the Docker run command. The main application logic can be found in `src/app.js`, where you can implement your database operations.
+
+## Contributing
