 ## Creating a Role for One or Multiple Accounts
 
-To create an IAM role that can be assumed in one or multiple AWS accounts, use either a CloudFormation Stack or StackSet and adapt the provided [template](https://github.com/prowler-cloud/prowler/blob/master/permissions/create_role_to_assume_cfn.yaml).
+To create an IAM role that can be assumed in one or multiple AWS accounts, use either a CloudFormation Stack or StackSet with the provided [template](https://github.com/prowler-cloud/prowler/blob/master/permissions/create_role_to_assume_cfn.yaml).
+
+The template requires the following parameters:
+
+- **AuthorisedARN:** The ARN of the user or role authorized to assume the created role (e.g., `arn:aws:iam::123456789012:root`)
+- **ExternalId:** A unique identifier to prevent the [confused deputy problem](https://docs.aws.amazon.com/IAM/latest/UserGuide/confused-deputy.html)
+- **ProwlerRoleName:** *(Optional)* Name of the IAM role (default: `ProwlerScanRole`)
+
+When running Prowler, include the External ID using the `-I/--external-id` flag:
+
+```sh
+prowler aws -R arn:aws:iam::<account_id>:role/<role_name> -I <external_id>
+```
 
 <Note>
 **Session Duration Considerations**: Depending on the number of checks performed and the size of your infrastructure, Prowler may require more than 1 hour to complete. Use the `-T <seconds>` option to allow up to 12 hours (43,200 seconds). If you need more than 1 hour, modify the _“Maximum CLI/API session duration”_ setting for the role. Learn more [here](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html#id_roles_use_view-role-max-session).
