+# Configure a security group's user members, referencing users by UPN
+
+This sample demonstrates use of the read-only [`Microsoft.Graph/Users` bicep type][users-ref] which allows you to
+fetch `user` resources by their user principal name (UPN).
+
+This quickstart creates a security group and adds users, referenced via their UPNs, as members.
+The list of users to be added as members are in a txt file, with each user's UPN on a separate line.
+Replace the UPN values in the example "userlist.txt" file with user UPN values from your tenant, before deployment.
+
+## Details
+
+This template sample:
+
+1. Creates a user UPN list from a txt file.
+2. Creates/updates a security group with its members set based on the user UPN list
+
+**NOTE:** Due to current modelling limitations [no more than 20 members can be added/updated at a time][20-members], and only [update semantics][update-only] are supported for members (and owners).
+
+### Prerequisites
+
+- A valid **Azure subscription**: If you don't own an Azure subscription, [create a free account](https://azure.microsoft.com/free/) before you begin.
+- An **Azure resource group** that you own under a valid Azure subscription, or [deploy without an Azure subscription][no-azure-sub].
+- [Bicep tools for authoring and deployment](https://learn.microsoft.com/graph/templates/quickstart-install-bicep-tools). The minimum required Bicep version is [v0.32.4](https://github.com/Azure/bicep/releases/tag/v0.32.4).
+- Have the requisite **Microsoft Entra roles** to deploy this template:
+
+  - Permissions to create security groups. [Users have this permission by default](https://learn.microsoft.com/entra/fundamentals/users-default-permissions#compare-member-and-guest-default-permissions). However, [admins can turn off this default](https://learn.microsoft.com/entra/fundamentals/users-default-permissions#restrict-member-users-default-permissions) in which case you need to be assigned at least the [Groups Administrator](https://learn.microsoft.com/entra/identity/role-based-access-control/permissions-reference#groups-administrator) role.
+
+### Deploy the Bicep template
+
+Before deploying the template, you **must** replace the UPN values in the example "userlist.txt" file with user UPN values from your tenant.
