+## Multi Account/Multi Region Deployment
+
+ACDP can be configured to enable cross-account deployment, thus enabling a Multi Account/Multi Region Deployment feature. In order to enable this feature, you need to provide values for certain CloudFormation Parameters when you deploy ACDP CloudFormation template. Detailed instructions are given in [Deployment Instructions](./deploy-the-solution.html) section.
+
+Upon succesfull deployment of ACDP, you need to deploy the [Guidance stack](https://github.com/aws-solutions/connected-mobility-solution-on-aws/blob/main/source/modules/acdp/guidance/README.md). This stack deploys SSM Parameters necessary to discover enrolled accounts and regions, as well as a StackSet configured to deploy AWS IAM roles necessary for ACDP to do cross-account deployments. This StackSet is automatically triggered when a new account is added to the enrolled Organizational Unit.
