However, for your own projects, we strongly advise pinning each module to the exact version\n\u003e you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic\n\u003e approach for updating versions to avoid unexpected changes.\n\n\n\n\n\n\n\n\n\u003c!-- markdownlint-disable --\u003e\n## Makefile Targets\n```text\nAvailable targets:\n\n  help                                Help screen\n  help/all                            Display help for all targets\n  help/short                          This help short screen\n  lint                                Lint terraform code\n\n```\n\u003c!-- markdownlint-restore --\u003e\n\u003c!-- markdownlint-disable --\u003e\n## Requirements\n\n| Name | Version |\n|------|---------|\n| \u003ca name=\"requirement_terraform\"\u003e\u003c/a\u003e [terraform](#requirement\\_terraform) | \u003e= 1.3 |\n| \u003ca name=\"requirement_aws\"\u003e\u003c/a\u003e [aws](#requirement\\_aws) | \u003e= 5.16 |\n\n## Providers\n\n| Name | Version |\n|------|---------|\n| \u003ca name=\"provider_aws\"\u003e\u003c/a\u003e [aws](#provider\\_aws) | \u003e= 5.16 |\n\n## Modules\n\n| Name | Source | Version |\n|------|--------|---------|\n| \u003ca name=\"module_this\"\u003e\u003c/a\u003e [this](#module\\_this) | cloudposse/label/null | 0.25.0 |\n\n## Resources\n\n| Name | Type |\n|------|------|\n| [aws_autoscaling_group.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/autoscaling_group) | resource |\n| [aws_autoscaling_policy.scale_down](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/autoscaling_policy) | resource |\n| [aws_autoscaling_policy.scale_up](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/autoscaling_policy) | resource |\n| [aws_cloudwatch_metric_alarm.all_alarms](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/cloudwatch_metric_alarm) | resource |\n| [aws_launch_template.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/launch_template) | resource |\n| [aws_subnet.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/subnet) | data source |\n\n## Inputs\n\n| Name | Description | Type | Default | Required |\n|------|-------------|------|---------|:--------:|\n| \u003ca name=\"input_additional_tag_map\"\u003e\u003c/a\u003e [additional\\_tag\\_map](#input\\_additional\\_tag\\_map) | Additional key-value pairs to add to each map in `tags_as_list_of_maps`.
