-### Description
-Description for home-assistant goes here.
+Home Assistant is an open-source home automation platform that puts local control and privacy first. It acts as a central hub for smart home devices, allowing for complex automation and integration across thousands of different brands.
 
-### Configuration
-- Path: templates/home-assistant/docker-compose.yml
-- Status: Draft
+Quick notes:
+
+- **Network Mode**: For many integrations (like discovery of smart bulbs or TVs), it is highly recommended to use `network_mode: host`.
+- **Persistence**: Ensure the `/config` directory is mapped to a persistent volume to save your configuration, dashboards, and integrations.
+- **Devices**: If you are using Zigbee or Z-Wave USB sticks, you will need to map the device path (e.g., `/dev/ttyUSB0`) into the container.
+
+Usage:
+
+1. Import the compose file into Portainer's Stacks or App Templates.
+2. Configure the volume mapping for the configuration folder.
+3. (Optional) Set the timezone environment variable (e.g., `TZ=America/New_York`).
+4. Deploy the stack via Portainer.
+5. Access the web interface at `http://<your-ip>:8123` to begin the onboarding process.
