+    ### Update the Static Account Map
+
+    Update the static account map in your organization's defaults file (`stacks/orgs/acme/_defaults.yaml`). This configuration provides account ID lookups for components that need them:
+
+    ```yaml
+    vars:
+      # Static account-map variable to replace the account-map component
+      # This provides account ID lookups for components that need them (e.g., cloudtrail)
+      # Set to false since we're using static mapping instead of the account-map component
+      account_map_enabled: false
+      account_map:
+        # Name of AWS partition
+        aws_partition: aws
+        # Name of the root account (used for organization management)
+        root_account_account_name: core-root
+        # Name of the audit account (used by components like cloudtrail)
+        audit_account_account_name: core-audit
+        # Identity account name (used by components like ecr)
+        identity_account_account_name: core-root
+        # Map of all account names (tenant-stage format) to their account IDs
+        # TODO: Automate population of this map (e.g., from account component outputs)
+        full_account_map:
+          core-artifacts: "__ARTIFACTS_ACCOUNT_NUMBER__"
+          core-audit: "__AUDIT_ACCOUNT_NUMBER__"
+          core-auto: "__AUTO_ACCOUNT_NUMBER__"
+          core-dns: "__DNS_ACCOUNT_NUMBER__"
+          core-network: "__NETWORK_ACCOUNT_NUMBER__"

+          plat-prod: "__PROD_ACCOUNT_NUMBER__"
+          plat-sandbox: "__SANDBOX_ACCOUNT_NUMBER__"
+          plat-staging: "__STAGING_ACCOUNT_NUMBER__"
+    ```
+
+    Replace each placeholder (e.g., `__ROOT_ACCOUNT_NUMBER__`) with the actual 12-digit AWS account ID from the output above.
+
+    :::caution Root Account Naming Convention
+    The `root_account_account_name` variable should always be set to `core-root` in your stack configuration, even if your actual AWS account has a different display name. This value is used internally by components for account lookups and must match the key in `full_account_map`.
+
+    To verify which account is your organization's management (root) account:
+    <Steps>
+    1. Navigate to [AWS Organizations → AWS accounts](https://console.aws.amazon.com/organizations/v2/home/accounts)
+    1. Look for the account labeled "Management account"
+    1. Use this account's ID for the `core-root` entry in `full_account_map`
+    </Steps>
+    :::
+
+    As you continue through the setup process, keep an eye out for other placeholder values in your stack configurations and replace them with actual values as needed.
