+- `$terraform plan -out $HOME/terraform-first-instance/name-of-plan.tf -target=module.name-of-module-to-run`
+
+You can also target multiple modules.
+
+- `$terraform plan -out $HOME/terraform-first-instance/name-of-plan.tf -target=module.name-of-module-to-run -target=module.name-of-other-module-to-run`
+
 **_(Note)_** `$terraform plan -out` writes the plan to a file and then `terraform apply` runs that plan.
 
-- `$terraform apply "$HOME/terraform-first-instance/terraform-plan.tf"`
