-# ArtNet Driver
+# 🎛️ ArtNet Driver
-Tecamino artNet driver DMX-Communication
+
+**Tecamino ArtNet Driver** — A lightweight driver for DMX communication using the ArtNet protocol over TCP/IP.
+
+This tool allows you to send DMX values to an ArtNet-compatible device, enabling remote lighting control and stage automation.
+
+---
+
+## 🚀 Features
+
+- 🔌 Sends DMX data over the ArtNet protocol (UDP)
+- 📁 Configurable working and config directories
+- 🐞 Optional debug logging for development and troubleshooting
+- ⚙️ Easy to run with CLI flags
+
+---
+
+## 🧰 Command Line Arguments
+
+| Flag              | Default     | Description                          |
+|-------------------|-------------|--------------------------------------|
+| `--port`          | `8110`      | Port on which the server listens     |
+| `--cfg`           | `./cfg`     | Path to the configuration directory  |
+| `--workingDirectory` | `"."`    | Working directory for runtime files  |
+| `--debug`         | `false`     | Enable verbose debug logging         |
+
+---
+
+## 🏁 Getting Started
+
+### 🔧 Run the Driver
+
+```bash
+go run main.go --port=8110 --cfg=./cfg --workingDirectory=. --debug=true
+
+```
+### 🔧 Build the App
+
+To compile the Go code into a runnable binary:
+
+#### On Linux or macOS:
+
+```bash
+go build -o artnet-driver
+```
