+The `icloud` platform allows you to detect presence using the [iCloud](https://www.icloud.com/) service. iCloud allows users to track their location on iOS devices.

+It does require that your device has beend registered with "Find My iPhone".
+
+To integrate iCloud in Home Assistant, add the following section to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+device_tracker:
+  platform: icloud
+  username: USERNAME
+  password: PASSWORD
+```
+
+Configuration variables:
+
+- **username** (*Required*): The username for the iCloud account.
+- **password** (*Required*): The password for your given username.
