+
+## 📖 Overview
+
+Infrastructure as Code (IaC) for the Comprofix homelab using [OpenTofu](https://opentofu.org/).  
+
+This repository provisions and manages resources such as the Proxmox VMs and LXC containers used in the Comprofix Homelab
+
+---
+
+## 🚀 Features
+
+- Declarative infrastructure management with OpenTofu
+- Remote state stored in PostgreSQL backend
+- Automated formatting, validation, and applies via GitHub Actions
+- Secure injection of secrets into `terraform.auto.tfvars`
+- Supports Proxmox VM provisioning and Omada configuration
+
+---
+
+## 📂 Repository Layout
+
+```
+├── dev-docker.tf # Docker VM definitions
+├── github.tf # GitHub repo/org configuration
+├── omada.tf # Omada network definitions
+├── provider.tf # Provider setup and backend configuration
+```
+
+---
+
+## ⚙️ Requirements
+
+- **OpenTofu** (installed automatically in GitHub Actions via [`opentofu/setup-opentofu`](https://github.com/opentofu/setup-opentofu))
+- **PostgreSQL** database for remote state  
+  Connection string provided via secret: `PG_CONN_STR`
+- **GitHub Actions self-hosted runner** with access to Proxmox and Omada APIs
+- Configured repository secrets:
+  - `PG_CONN_STR`
+  - `CI_USER`, `CI_PASSWORD`
+  - `PVE_API_URL`, `PVE_API_TOKEN_ID`, `PVE_API_TOKEN_SECRET`
+  - `SSH_PRIVATE_KEY`, `SSH_PASSPHRASE`
+
+---
+
+## 🔄 Workflow
+
+Infrastructure is applied automatically on pushes to the `main` branch.
+
+1. Checkout repo
+2. Generate `terraform.auto.tfvars` from GitHub secrets
+3. Run `tofu init`, `tofu fmt`, `tofu validate`
+4. Execute `tofu plan`
+5. If successful, run `tofu apply`
+
+> 🔒 PRs and forks do not run workflows. Only code merged into `main` will trigger an apply.
+
+---
+
+## 📖 Usage
+
+Local testing:
+
+```bash
+# Initialize
+tofu init
+
+# Format configs
+tofu fmt -recursive
+
+# Validate configs
+tofu validate
+
+# Plan changes
+PG_CONN_STR="postgres://..." tofu plan
+
+# Apply changes
+PG_CONN_STR="postgres://..." tofu apply
