+# cfn-deploy example
+
+Example uses aws-action `configure-aws-credentials` with OIDC federation. Prior
+to using this example project, the user needs to deploy the
+[github-actions-oidc-federation-and-role](../federated-setup/github-actions-oidc-federation-and-role.yml)
+template in the AWS account they want to deploy the CloudFormation template
+into. Specify the GitHub Organization name, repository name, and the specific
+branch you want to deploy on.
+
+Within the [github/workflows](./.github/workflows/) directory there is a
+[compliance.yml](./.github/workflows/compliance.yml) and a
+[deploy.yml](./.github/workflows/deploy.yml). The deploy.yml file leverages the
+aws-action `configure-aws-credentials` and accesses GitHub Action Secrets for
+some of the variables. The compliance.yml runs static application security
+testing using cfn-guard.
+
+To use the example you will need to set the following GitHub Action Secrets:
+
+| Secret Key      | Used With                        | Description                              |
