+This repository contains scripts for installing **Prometheus**, various **exporters**, **Grafana** and **Loki**. The goal is to **simplify the monitoring setup**, making it quick and efficient to go from **installation to viewing detailed reports in Grafana** about the **OpenHistoricalMap** infrastructure.
 
 ## Authentication for Prometheus
 
-Before installing Prometheus, create basic authentication credentials for the Prometheus endpoint:
+Before installing **Prometheus**, set up **basic authentication credentials** for the Prometheus endpoint:
 
 ```sh
 htpasswd -c auth prometheus-user
 kubectl create secret generic prometheus-basic-auth --from-file=auth -n monitoring
 ```
 
-After this step, you can proceed with Prometheus installation and configure the Ingress to use this basic authentication.
+Once authentication is configured, you can proceed with Prometheus installation and configure Ingress to use these credentials.
