 # Basic Monitoring System with Grafana and Prometheus
 
-This project sets up a basic monitoring system using Grafana and Prometheus with Docker.
+This project sets up a monitoring system using Grafana and Prometheus with Docker. It includes CI/CD configuration with GitHub Actions to ensure the services are always up-to-date and functioning correctly.
+
+## Features
+
+- **Prometheus**: Collects and stores metrics.
+- **Grafana**: Visualizes the metrics collected by Prometheus.
+- **Node Exporter**: Provides OS metrics for Prometheus.
+- **Alertmanager**: Manages alerts sent by Prometheus.
+- **CI/CD with GitHub Actions**: Automates the deployment and testing of the system.
+
+## Prerequisites
+
+- Docker and Docker Compose installed on the system.
+- A Docker Hub account.
+- Environment variables configured for Docker Hub and Grafana authentication.
+
+## Configuration
+
+### Environment Variables
+
+Create a `.env` file in the root of the project with the following variables:
+GF_SECURITY_ADMIN_USER=admin
+GF_SECURITY_ADMIN_PASSWORD=admin
 
 ## Instructions
 
 1. Clone the repository.
 2. Navigate to the project folder.
-3. Run `docker-compose up`.
-4. Access Grafana at `http://localhost:3000`
+3. Create a .env file in the root directory with the necessary environment variables.
+4. Run docker-compose up -d to start the services.
+5. Access Prometheus at http://localhost:9090.
+6. Access Grafana at http://localhost:3000 and use the credentials defined in the .env file.
+
+## CI/CD
+
+The CI/CD pipeline is defined in .github/workflows/ci-cd.yml and performs the following actions:
+
+- Builds and pushes Docker images.
+- Deploys the system using Docker Compose.
+- Checks that the services are running correctly.
+- Checks that the out of the box dashboards are working with data from the datasource(prometheus).
+
+
+### Setting Up GitHub Secrets
+
+To set up GitHub secrets for the CI/CD pipeline, follow these steps:
+
+1. Navigate to your forked repository on GitHub.
+2. Go to **Settings** > **Secrets and variables** > **Actions**.
+3. Add the following secrets:
+   - `DOCKER_USERNAME`: Your Docker Hub username.
+   - `DOCKER_PASSWORD`: Your Docker Hub password.
+   - `GF_SECURITY_ADMIN_USER`: Your Grafana admin username.
+   - `GF_SECURITY_ADMIN_PASSWORD`: Your Grafana admin password.
+
+
+## Monitoring
+
+- Prometheus: Access Prometheus at http://localhost:9090.
+- Grafana: Access Grafana at http://localhost:3000 and use the credentials defined in the .env file.
