 # Terraform Azure Bootcamp
+
+This repo contains hands-on Terraform projects on Azure, following a structured learning path:
+1. Foundations (VM, Virtual Network)
+2. Modules
+3. Remote State & Environments
+4. Scaling & Advanced Patterns
+5. Security & Testing
+6. Production-Ready 3-Tier Architecture
+
+## 📂 Structure
+- `modules/` → reusable Terraform modules (network, compute, database, etc.)
+- `environments/` → environment-specific configs (`dev`, `prod`)
+- `.github/workflows/terraform.yml` → CI/CD with GitHub Actions
+
+## 🚀 Usage
+```bash
+cd environments/dev
+terraform init
+terraform plan
+terraform apply
