-# Homelab
+# 🧪 Homelab
 
-Hello world !
+> ⚠️ **Work in Progress** – This repository is actively evolving as I automate and expand my homelab.
+
+Welcome to my homelab repository! This is where I manage and document the infrastructure powering my personal lab environment using modern DevOps tools and best practices.
+
+## 🚀 Goals
+
+- Automate VM and infrastructure deployment with **Terraform**
+- Configure systems and services using **Ansible**
+- Deploy and manage Kubernetes with **Flux CD** using a **GitOps** approach
+- Keep everything **declarative**, **reproducible**, and **version-controlled**
+
+## 📌 Notes
+
+This repository is intended for **educational and experimental purposes**. Feel free to explore, fork, and adapt ideas for your own homelab setup.
+
+---
+
+Stay tuned — more coming soon! 🚧
