+This application is in place to help test the SwiftUI Google Sign-in button.
+Tests are run via an example application, `GoogleSignInSwiftButtonExample`.
+These tests rely on an `XCUIApplication` instance that will launch the app.
+
+# Usage
+
+## Testing
+
+Open `GoogleSignInSwiftButtonExample.xcodeproj` and type "command-u" to
+execute the tests.
+
+## Running the App
+
+The app isn't very interesting right now; it simply displays an instance of
+`GoogleSignInButton` that increments a counter upon tap.
+Nonetheless, if you would like to run this app, all you need to do is open
+`GoogleSignInSwiftButtonExample.xcodeproj` and hit run.
