+## CDK Deployment
 
+• Bootstrap CDK (first time only): npx cdk bootstrap aws://482311766496/me-central-1
+• List available stacks: npx cdk list
+• Deploy web: npx cdk deploy --require-approval never
+• View changes before deploy: npx cdk diff
+• Generate CloudFormation template: npx cdk synth
+• Destroy infrastructure: npx cdk destroy
+• Web infrastructure is configured in infrastructure/web-stack.ts
+• After code changes: build Flutter web app and deploy to hosting service
