 # HA_ProcessMining_Addon
-Brings Process Mining to Home Assistant as Add-On!
+Brings Process Mining to Home Assistant as an Add-on.
 
-This repository provides Home Assistant Addon for Process Mining.
+This repository is a Home Assistant deployment wrapper for the actual
+[SmartHomeProcessMining](https://github.com/FelixMarschall/SmartHomeProcessMining)
+application.
+
+## Why Process Mining on Smart Home Data?
+Process mining turns event logs into understandable models of real-world behavior.
+Smart homes already generate rich logs through device state changes and automations,
+so you can use these techniques to:
+
+- Discover real routines and occupancy patterns
+- Spot anomalies or inefficiencies in automation flows
+- Optimize energy usage based on actual device sequences
+- Visualize how daily processes evolve over time
+
+The motivation for this project is to bring these analytical insights to Home
+Assistant users so they can understand and improve their smart home behavior
+using the existing logbook data.
 
 ## Installation
 [![Open your Home Assistant instance and show the add add-on repository dialog with a specific repository URL pre-filled.](https://my.home-assistant.io/badges/supervisor_add_addon_repository.svg)](https://my.home-assistant.io/redirect/supervisor_add_addon_repository/?repository_url=https%3A%2F%2Fgithub.com%2FFelixMarschall%2FHA_ProcessMining_Addon)
 
-Guide for Home Assistant Addon configuration:  [DOCS](../main/process_management/DOCS.md)
+Guide for Home Assistant Add-on configuration: [DOCS](./process_management/DOCS.md)
 
 Installation without Home Assistant environment: [SmartHomeProcessMining](https://github.com/FelixMarschall/SmartHomeProcessMining)
 
 ## Project Structure
-This repository depends on the submodule [SmartHomeProcessMining](https://github.com/FelixMarschall/SmartHomeProcessMining),
-which can run locally and access the Home Assistant logbook remotely.
+This repository mainly contains the Home Assistant add-on packaging and points to
+the real application via a git submodule.
+
+- `process_management/`: Home Assistant add-on definition, Dockerfile, and `config.yaml`.
+- `process_management/app/SmartHomeProcessMining/`: git submodule with the actual
+  process mining application code.
+- `repository.yaml`: metadata for the Home Assistant add-on repository.
 
-The `process_management` folder contains the Docker build files and `config.yaml` for Home Assistant.
+Because the application lives in the submodule, you need to initialize it when
+working locally:
 
+```bash
+git submodule update --init --recursive
+```
