-## Draft code
-This version of PVEMod is as draft version and may or may not be fully functional.
-The installer is currently not working and is work in progress.
+# node_info
+
+Extends the Proxmox VE node status view with live hardware sensor data. A background daemon collects data from the configured sources and exposes it through the PVE API.
+
+## Features
+
+### Temperature Sensors (lm-sensors)
+
+Reads hardware sensor data via `lm-sensors` and enriches each chip/adapter entry with context.
+
+### NVIDIA GPU
+
+Polls `nvidia-smi` on a configurable interval. Supports multiple GPUs. Metrics stored in RRD for historical graphing.
+
+| Metric | Unit |
+|--------|------|
+| GPU temperature | °C |
+| GPU utilisation | % |
+| Memory utilisation | % |
+| Memory used / total | MiB |
+| Power draw / limit | W |
+| Fan speed | % |
+
+### Intel GPU
+
+Polls `intel_gpu_top` for each detected Intel GPU card. Metrics stored in RRD for historical graphing.
+
+| Metric | Unit |
+|--------|------|
+| Requested / actual frequency | MHz |
+| Interrupt rate | irq/s |
+| RC6 residency | % |
+| GPU power / package power | W |
+| Engine busy/semaphore/wait (Render, Blitter, Video, VideoEnhance) | % |
+
+### AMD GPU
+
+Placeholder — device discovery and collection are not yet implemented.
+
+### UPS (Network UPS Tools)
+
+Polls `upsc` for a configured NUT device and exposes all key-value pairs returned by the daemon. Supports any UPS accessible via NUT (local or remote).
+
+Configuration: `device_name=ups@localhost`
+
+### System Information
+
+Reads hardware identity from `dmidecode` (cached at configure time, no runtime root required).
+
+| `type` | Data source | Fields exposed |
+|--------|-------------|----------------|
+| `1` | DMI System | Manufacturer, Product Name, Serial Number |
+| `2` | DMI Baseboard | Manufacturer, Product Name, Serial Number |
+
+## Requirements
+
+Each feature requires the corresponding tool to be installed on the Proxmox host:
+
+| Feature | Required tool |
+|---------|---------------|
+| Temperature sensors | `lm-sensors` (`sensors` binary) |
+| NVIDIA GPU | `nvidia-smi` |
+| Intel GPU | `intel-gpu-tools` (`intel_gpu_top` binary) |
+| UPS | `nut-client` (`upsc` binary) |
+| System information | `dmidecode` (run once via `pve-mod-configure`) |
+
+## Debug Mode
+
+Each collector supports a debug mode that reads from a local file instead of executing the real tool. Useful for development and testing without physical hardware.
