+For a practical example of how to set up and run your XCTest and XCUITest plans on Sauce Labs infrastructure, you can refer to
+the [demo-xctest repository](https://github.com/saucelabs-training/demo-xctest).
+
+This repository contains multiple examples of how to run XCTest plan on Sauce Labs cloud, along with the source code for the demonstration app
+used in these examples. By leveraging `xctestplan` and `xctestrun` configuration files, this demo shows how to execute an XCTest plan, similar to
+using the following xcodebuild command:
+
+```shell
+xcodebuild test-without-building -xctestrun $(PATH_TO_XCTESTRUN_FILE)
+```
+
+Visit the repo to see how everything is configured and try running your own XCTest plan on Sauce Labs' real devices.
