+# Quickstart: Add resources or resource containers to service groups with Service Group Member Relationships in Portal 
+ 
+To add resources, resource groups, or subscriptions to a Service Group (preview), you need to create a new Service Group Member Relationship. For more information on service groups, see [Getting started with Service Groups](overview.md).
+
+> [!IMPORTANT]
+> Azure Service Groups is currently in PREVIEW. 
+> See the [Supplemental Terms of Use for Microsoft Azure Previews](https://azure.microsoft.com/support/legal/preview-supplemental-terms/) for legal terms that apply to Azure features that are in beta, preview, or otherwise not yet released into general availability.
+
+## Prerequisites
+
+- If you don't have an Azure subscription, create a [free](https://azure.microsoft.com/free/)
+  account before you begin.
+
+- To be able to deploy a service group member relationship, you must have Microsoft.Relationship/ServiceGroupMember/write permissions on member resource and [Service Group Contributor](../../role-based-access-control/built-in-roles/management-and-governance.md) at the target service group. 
+
+## Add members during service group creation 
+
+1. When creating a new Service Group, there's an available `Members` tab to add resources.

+
+2. Select to add individual resources, resource groups, or subscriptions. 
+
+3. Once selected, you can use filters to narrow the list as needed. 
+
+4. Once all members are chosen, press **Select**
+
+5. All members to be added are displayed in the list.

+
+2. Select **All services** > **Management + governance**.
+
+3. Select **Service Groups**.
+
+4. Select the desired Service Group. 
+
+5. In the left hand side service menu, select **members** under relationship management. 
+
+:::image type="content" source="./media/members-service-menu.png" alt-text="Screenshot of the relationship management drop down within the left hand context pane on the service group page." Lightbox="./media/members-service-menu.png":::
+

+
+
+## Remove members to existing service group
+

+
+5. In the left hand side service menu, select **members** under relationship management.
