-This action requires Terraform plan files in JSON format for scanning.
+
+This GitHub action identifies insecure configurations in Infrastructure as Code (IaC) files for Google Cloud resources. This action requires Terraform plan files in JSON format for scanning.
+
 
 Use this action to detect and remediate issues in IaC files for Google Cloud before you deploy the resources.
 
+
 This action lets you:
 - Scan IaC template files (such as Terraform plan files).
 - Display issues with their severity as a SARIF Report in the GitHub Workspace after a scan completes.
 - Define severity-based failure criteria for passing or failing the build.
 
-> [!NOTE] 
-> This is a Security Command Center Premium tier offering for subscription customers only. You must activate the Security Command Center Premium tier in the Google Cloud organization to use this feature.

 **This is not an officially supported Google product, and it is not covered by a
 Google Cloud support contract. To report bugs or request features in a Google
 Cloud product, please contact [Google Cloud
 support](https://cloud.google.com/support).**

+
+> [!CAUTION]
+> Don’t enter any sensitive information such as passwords and other personal identifiable information in the Terraform plan files.

 ## Prerequisites
 
--   This action requires a Google Cloud service account which has the 
-    **Security Posture Shift-Left Validator** role or the **Security 
-    Posture Admin** role on the Google Cloud organization that includes 
-    the IaC resources. For more information, see [Authorization](#authorization).
 
--   This action runs using Node 20. If you are using self-hosted GitHub Actions
-    runners, you must use a [runner
-    version](https://github.com/actions/virtual-environments) that supports this
-    version or later.

 ## Inputs
 
--   `organization_id`: (Required) The Google Cloud organization ID for the 
-    organization which includes the resources that you want to modify.
 
--   `scan_file_ref`: (Required) The absolute file path, including the file name, 
-    for the IaC file in the workspace. For example: './tf_plan.json', or 
-    './artifacts/tf_plan.json'.
+* `organization_id`: (Required) The Google Cloud organization ID for the organization which includes the resources that you want to modify.
+
+
+* `scan_file_ref`: (Required) The absolute file path, including the file name, for the IaC file in the workspace. For example: './tf_plan.json', or './artifacts/tf_plan.json'.
+
+
+* `iac_type`: (Required) The IaC template type. Currently only Terraform is supported.
 
--   `iac_type`: (Required) The IaC template type. Currently only Terraform is
-    supported.
 
--   `iac_version`: (Required) The IaC template version. For example: '1.6.6', 
-    or '1.6.5'.
+* `iac_version`: (Required) The IaC template version. For example: '1.6.6',  or '1.6.5'.
 
--   `scan_timeout`: (Optional) The maximum time before the action stops. 
-    The time must be between '1m' and '10m'. The default is `1m`.
 
--   `ignore_violations`: (Optional) Whether violations found in IaC file 
-    should be ignored when determining the build status. This input doesn’t 
-    apply to  violations that are related to generating SARIF reports and 
-    determining the `iac_scan_result`. The default is `false`.
+* `scan_time_out`: (Optional) The maximum time before the action stops. The time must be between '1m' and '10m'. The default is `1m`.
 
--   `failure_criteria`: (Optional) The failure criteria that determines the 
-    workflow build status. You can set a threshold for the number of critical, 
-    high, medium, and low severity issues and use an aggregator  (either `and` 
-    or `or`) to evaluate the criteria. To determine whether a build has failed, 
-    the threshold for each severity is evaluated against the count of issues 
-    with that severity in the IaC scan results and then severity level evaluations 
-    are aggregated using `AND` or `OR` to arrive at `failure_criteria` value.
 
-    If the `failure_criteria` evaluates to `true`, the workflow is marked as 
-    `FAILED`. Otherwise, the workflow is marked as `SUCCESS`. The default is 
-    "Critical:1, High:1, Medium:1, Low:1, Operator:OR".
+* `ignore_violations`: (Optional) Whether violations found in IaC file should be ignored when determining the build status. This input doesn’t apply to  violations that are related to generating SARIF reports and determining the `iac_scan_result`. The default is `false`.

To determine whether a build has failed, the threshold for each severity is evaluated against the count of issues with that severity in the IaC scan results and then severity level evaluations are aggregated using `AND` or `OR` to arrive at `failure_criteria` value.
+
+
+If the `failure_criteria` evaluates to `true`, the workflow is marked as `FAILED`. Otherwise, the workflow is marked as `SUCCESS`. The default is "Critical:1, High:1, Medium:1, Low:1, Operator:or".
+
+
+* `fail_silently`: (Optional) Whether the workflow passes when an internal error (such as an invalid credential or plugin dependency failure) occurs. Note: The action always fails when the input is invalid. The default is `false`.
 
--   `fail_silently`: (Optional) If set to true, workflow will not fail in case
-    of any internal error including invalid credentials and plugin dependency
-    failure. Note: Action will always fail in case of any input validation
-    failure. Default: false.
 
 ## Outputs
 
--   `iac_scan_result`: The result of the security scan. One of:
 
-    1.  `passed` - No violations were found or the `failure_criteria` was not
-        satisfied.
-    2.  `failed` - The `failure_criteria` was satisfied.
-    3.  `error` - The action ran into an execution error, generally 
-        due to a misconfiguration or invalid credentials.
+* `iac_scan_result`: The result of the security scan. One of:

+2. `failed` - The `failure_criteria` was satisfied.
+3. `error` - The action ran into an execution error, generally due to a misconfiguration or invalid credentials.
+
+
+* `iac_scan_result_sarif_path`: The path for the SARIF report file. This file is only available when violations are found in the scan file.
 
--   `iac_scan_result_sarif_path`: The path for the SARIF report file. This 
-    file is only available when violations are found in the scan file.
