## What it is
A Linux kernel driver and Python GUI/CLI tools for controlling Lenovo Legion laptop hardware features such as fan curves, power modes, power limits, and rapid charging. It serves as a Linux alternative to Lenovo Vantage, built via reverse engineering of the ACPI firmware and embedded controller.

## Use cases
- control fan curve on Lenovo Legion laptop in Linux
- set power mode and power limits from Linux
- enable rapid charging or conservation mode on Legion
- replace Lenovo Vantage on Linux
- monitor and control laptop fans on Ubuntu or Arch
- reduce fan noise on Lenovo gaming laptop

## When to choose
- you own a Lenovo Legion (or similar IdeaPad) laptop running Linux and want hardware control
- you need fan curve, power mode, or charging control that the stock kernel doesn't expose
- you want an open-source alternative to Lenovo Vantage or Legion Zone

## When to avoid
- you use Windows or macOS - this is Linux-only
- your laptop model is not a Lenovo Legion/IdeaPad with supported EC firmware
- you need a fully upstreamed solution without building or installing a kernel module
