+# saucectl TestCafe & React Example
+
+This example demonstrates how to use a test time dependency when running your
+TestCafe tests with saucectl.
+
+## What You'll Need
+
+The steps below illustrate one of the quickest ways to get set up. If you'd like
+a more in-depth guide, please check out our 
+[documentation](https://docs.saucelabs.com/dev/cli/saucectl/#installing-saucectl).
+
+### Install `saucectl`
+
+```sh
+npm install -g saucectl
+```
+
+### Set Your Sauce Labs Credentials
+
+```sh
+saucectl configure
+```
+
+## Running The Examples
+
+Simply check out this repo, navigate into `examples/react` and run the
+command below :rocket:
+
+```sh
+saucectl run
+```
+
+## Configuration
+
+The test in this example requires the
+[testcafe-react-selectors](https://github.com/DevExpress/testcafe-react-selectors)
+package so it needs to be available in the test environment. We can define a
+list of packages to install before test execution in the saucectl configuration
+file.
+
+```yaml
+npm:
+  usePackageLock: true
+```
+
+Enabling the `usePackageLock` option ensures that the project's package.json and
+package-lock.json are used during package installation. In most cases, this will
+reduce the time needed for package installation.
