+# Mosquitto (MQTT Broker) – Kubernetes Deployment
+
+This repository contains a minimal and production-friendly deployment of an MQTT broker using Eclipse Mosquitto.
+
+It is intended to be used with services like:
+- Home Assistant
+- Frigate
+- IoT devices
+- Custom automations
+
+---
+
+## 📦 Overview
+
+Mosquitto is a lightweight MQTT broker used for message-based communication between services.
+
+In this setup:
+- Mosquitto acts as the central message bus
+- Frigate publishes events (e.g. detections)
+- Home Assistant subscribes to these events
+
+---
+
+## 🧱 Architecture
