+# Unified Service Failure Notifier
+
+## Description
+
+This role installs a systemd service that sends notifications via both [sys-ctl-alm-telegram](../sys-ctl-alm-telegram/README.md) and [sys-ctl-alm-email](../sys-ctl-alm-email/README.md) when any service fails.
+
+## Overview
+
+Optimized for prompt and comprehensive failure alerts, this role configures a unified notification service. It leverages the capabilities of both Telegram and Email notifications to ensure that administrators are quickly informed about service issues, enabling rapid troubleshooting.
+
+## Purpose
+
+The primary purpose of this role is to provide a centralized mechanism for service failure notifications. By integrating with both the Telegram and Email notifier roles, it delivers reliable alerts through multiple channels, enhancing overall system observability and responsiveness.
+
+## Features
+
+- **Unified Notification Service:** Installs a systemd service that triggers both Telegram and Email alerts.
+- **Dependency Integration:** Works seamlessly with the [sys-ctl-alm-telegram](../sys-ctl-alm-telegram/README.md) and [sys-ctl-alm-email](../sys-ctl-alm-email/README.md) roles.
+- **Automated Service Management:** Automatically restarts the notifier service upon configuration changes.
+- **Centralized Alerting:** Provides a unified approach to monitor and notify about service failures.
