+- Ponovi za `vm_bravo`, `vm_charlie`, `vm_delta` po potrebi.
+
+## Provera i gašenje
+- `terraform state list`  # pregled aktivnih resursa u ovom projektu
+- `terraform destroy -target=proxmox_virtual_environment_vm.vm_alpha`  # gasi samo jednu mašinu
+- `terraform destroy`  # gasi sve instance iz ovog foldera kada završiš
+
+## Dodatno
+- Ako budeš delio state, pređi na remote backend (S3 + DynamoDB lock, Terraform Cloud…) pre proizvodnog korišćenja.
+- Za promenu gateway-a koristi varijablu `vm_gateway` u `terraform.tfvars`.
