 To create a new device:
 1. In the left pane select **Devices**, then select **+New**.
 1. Leave **Device template** set to *Unassigned*.
 
-    > [!NOTE]
-    > In this quickstart for simplicity, you connect a simulated device that uses an unassigned template. If you continue using IoT Central to manage devices, you'll learn about using device templates. For an overview of working with device templates, see [Quickstart: Add a simulated device to your IoT Central application](../articles/iot-central/core/quick-create-simulated-device.md).
 1. Set a friendly **Device name** and **Device ID**. Optionally, use the generated values.
