+# Trusted AI Demo - OpenTofu Infrastructure
+
+This project contains OpenTofu/Terraform configuration for the Trusted AI Demo infrastructure on Azure.
+
+## Infrastructure Components
+
+This configuration creates:
+
+- **Resource Group**: Container for all Azure resources
+- **Virtual Network**: 10.0.0.0/16 address space
+- **Subnet**: 10.0.1.0/24 for VM placement
+- **Network Security Group**: With RDP (port 3389) rule for remote access
+- **Public IP**: Static public IP for VM access
+- **Network Interface**: Connects VM to the virtual network
+- **Windows Server 2022 VM**: Standard_B2s (2 vCPUs, 4 GB RAM)
+
+## Prerequisites
+
+- [OpenTofu](https://opentofu.org/) >= 1.0 or [Terraform](https://www.terraform.io/) >= 1.0
+- Azure CLI configured with appropriate credentials
+- Azure subscription with necessary permissions
+
+## Getting Started
+
+### 1. Authenticate with Azure
+
+```bash
+az login
+az account set --subscription "<your-subscription-id>"
+```
+
+### 2. Initialize OpenTofu
+
+```bash
+tofu init
+```
+
+Or if using Terraform:
+
+```bash
+terraform init
+```
+
+### 3. Review the Plan
+
+```bash
+tofu plan
+```
+
+### 4. Apply the Configuration
+
+```bash
+tofu apply
+```
+
+## Project Structure
+
+- `main.tf` - Main infrastructure configuration
+- `variables.tf` - Input variable definitions
+- `outputs.tf` - Output value definitions
+- `terraform.tfvars.example` - Example variable values (copy to `terraform.tfvars`)
+
+## Configuration
+
+### Required Configuration
+
+1. Copy the example variables file:
+   ```bash
+   cp terraform.tfvars.example terraform.tfvars
+   ```
+
+2. Edit `terraform.tfvars` and set your admin password:
+   ```hcl
+   admin_password = "YourSecurePassword123!"
+   ```
+
+   **Important**: The password must be at least 12 characters long and contain uppercase, lowercase, and numbers.
+
+3. **Security Recommendation**: Change `allowed_rdp_source` to your public IP address instead of `"*"`:
+   ```hcl
+   allowed_rdp_source = "YOUR_PUBLIC_IP/32"
+   ```
+
+   You can find your public IP with:
+   ```bash
+   curl ifconfig.me
+   ```
+
+### Optional Customization
+
+You can also customize:
+- `resource_group_name`: Name of the resource group
+- `location`: Azure region (default: westeurope)
+- `vm_name`: Name of the virtual machine
+- `vm_size`: VM size (default: Standard_B2s)
+- `vnet_address_space`: Virtual network address space
+- `subnet_address_prefix`: Subnet address prefix
+
+## Connecting to the VM
+
+After the infrastructure is created, you can connect to the Windows VM via RDP:
+
+1. Get the public IP address:
+   ```bash
+   tofu output vm_public_ip
+   ```
+
+2. Connect using Remote Desktop:
+   - **Windows**: Use the connection string from output:
+     ```bash
+     tofu output rdp_connection_string
+     ```
+   - **macOS**: Use Microsoft Remote Desktop app
+   - **Linux**: Use Remmina or similar RDP client
+
+3. Login credentials:
+   - Username: The value you set for `admin_username` (default: azureadmin)
+   - Password: The password you set in `terraform.tfvars`
+
+## Cleanup
+
+To destroy all resources:
+
+```bash
+tofu destroy
+```
+
+**Warning**: This will permanently delete all resources created by this configuration.
