+# lapctl
+
+**lapctl** is an upcoming command-line utility written in Rust for managing laptop hardware features on Linux.
+
+It aims to provide a simple and unified interface for controlling hybrid GPU modes, battery charging limits, and other laptop power features directly from the terminal.
+
+---
+
+## Planned Features
+
+- Switch GPU modes on hybrid graphics laptops
+  - Integrated GPU
+  - Hybrid mode
+  - NVIDIA GPU
+
+- Set and manage battery charging limits
+- View laptop hardware and power status
+- Lightweight and fast CLI interface
+- Designed for Linux systems with hybrid GPUs (Optimus)
+
+---
+
+## Project Status
+
+**Work in progress**
+
+This project is currently in early development.
+Features, commands may change as development progresses.
+
+---
+
+## Goals
+
+- Provide a **simple CLI interface** for laptop hardware management
+- Support **hybrid GPU laptops (Intel + NVIDIA / AMD + NVIDIA)**
+- Offer **battery health features like charge limit control**
+- Be **lightweight, fast, and easy to use**
+
+---
+
+## Example CLI (Planned)
+
+```bash
+lapctl gpu integrated
+lapctl gpu hybrid
+lapctl gpu nvidia
+
+lapctl battery limit 80
+lapctl battery status
+
+lapctl status
+```
+
+---
+
+## Built With
+
+- Rust
+- Modern Linux system interfaces
