+## Configuration Management
+
+**Note on Smart Shield Evolution:** Argo Smart Routing is being integrated into Smart Shield. Configuration methods below remain valid; Terraform and IaC patterns unchanged.
+
+### Infrastructure as Code (Terraform)
+
+```hcl
+# terraform/argo.tf
+# Note: Use Cloudflare Terraform provider
+
+resource "cloudflare_argo" "example" {
+  zone_id        = var.zone_id
+  smart_routing  = "on"
+  tiered_caching = "on"
+}
+
+variable "zone_id" {
+  description = "Cloudflare Zone ID"
+  type        = string
+}
+
+output "argo_enabled" {
+  value       = cloudflare_argo.example.smart_routing
+  description = "Argo Smart Routing status"
+}
+```
+
+### Environment-Based Configuration
+
+```typescript
+// config/argo.ts
+interface ArgoEnvironmentConfig {
+  enabled: boolean;
+  tieredCache: boolean;
+  monitoring: {
+    usageAlerts: boolean;
+    threshold: number;
+  };
+}
+
+const configs: Record<string, ArgoEnvironmentConfig> = {
+  production: {
+    enabled: true,
+    tieredCache: true,
+    monitoring: {
+      usageAlerts: true,
+      threshold: 1000, // GB
+    },
+  },
+  staging: {
+    enabled: true,
+    tieredCache: false,
+    monitoring: {
+      usageAlerts: false,
+      threshold: 100, // GB
+    },
+  },
+  development: {
+    enabled: false,
+    tieredCache: false,
+    monitoring: {
+      usageAlerts: false,
+      threshold: 0,
+    },
+  },
+};
+
+export function getArgoConfig(env: string): ArgoEnvironmentConfig {
+  return configs[env] || configs.development;
+}
+```
+
+### Pulumi Configuration
+
+```typescript
+// pulumi/argo.ts
+import * as cloudflare from '@pulumi/cloudflare';
+
+const zone = new cloudflare.Zone('example-zone', {
+  zone: 'example.com',
+  plan: 'enterprise',
+});
+
+const argoSettings = new cloudflare.Argo('argo-config', {
+  zoneId: zone.id,
+  smartRouting: 'on',
+  tieredCaching: 'on',
+});
+
+export const argoEnabled = argoSettings.smartRouting;
+export const zoneId = zone.id;
+```
+
+## Billing Configuration
+
+Before enabling Argo Smart Routing, ensure billing is configured for the account:
+
+**Prerequisites:**
+1. Valid payment method on file
+2. Enterprise or higher plan
+3. Zone must have billing enabled
+
+**Check Billing Status via Dashboard:**
+1. Navigate to Account → Billing
+2. Verify payment method configured
+3. Check zone subscription status
+
+**Note:** Attempting to enable Argo without billing configured will result in `editable: false` in API responses.
+
+## Environment Variable Setup
+
+**Required Environment Variables:**
+```bash
+# .env
+CLOUDFLARE_API_TOKEN=your_api_token_here
+CLOUDFLARE_ZONE_ID=your_zone_id_here
+CLOUDFLARE_ACCOUNT_ID=your_account_id_here
+
+# Optional
+ARGO_ENABLED=true
+ARGO_TIERED_CACHE=true
+```
+
+**TypeScript Configuration Loader:**
+```typescript
+// config/env.ts
+import { z } from 'zod';
+
+const envSchema = z.object({
+  CLOUDFLARE_API_TOKEN: z.string().min(1),
+  CLOUDFLARE_ZONE_ID: z.string().min(1),
+  CLOUDFLARE_ACCOUNT_ID: z.string().min(1),
+  ARGO_ENABLED: z.string().optional().default('false'),
+  ARGO_TIERED_CACHE: z.string().optional().default('false'),
+});
+
+export const env = envSchema.parse(process.env);
+
+export const argoConfig = {
+  enabled: env.ARGO_ENABLED === 'true',
+  tieredCache: env.ARGO_TIERED_CACHE === 'true',
+};
+```
+
+## CI/CD Integration
+
+**GitHub Actions Example:**
+```yaml
+# .github/workflows/deploy-argo.yml
+name: Deploy Argo Configuration
+
+on:
+  push:
+    branches: [main]
+    paths:
+      - 'terraform/argo.tf'
+
+jobs:
+  deploy:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      
+      - name: Setup Terraform
+        uses: hashicorp/setup-terraform@v2
+        
+      - name: Terraform Init
+        run: terraform init
+        working-directory: ./terraform
+

+        run: terraform apply -auto-approve
+        working-directory: ./terraform
+        env:
+          CLOUDFLARE_API_TOKEN: ${{ secrets.CLOUDFLARE_API_TOKEN }}
