+# 🐳 Docker Setup Script for Debian
+
+This script automates the installation of Docker and optionally helps you set up a working directory and a `compose.yaml` as well as a `.env` file.
+
+---
+
+## 🚀 How to Use
+
+run the following script
+
+```bash
+wget -qO docker-debian.sh https://gitea.featherer.xyz/nono/docker-debian/raw/branch/main/docker-debian.sh
+source docker-debian.sh
+```
+
+Or when run locally (using your own ip address)
+
+```bash
+wget -qO docker-debian.sh http://10.1.0.102:3000/nono/docker-debian/raw/branch/main/docker-debian.sh
+source docker-debian.sh
