@@ -7,3 +7,28 @@ Geb Functional Testing for Grails 3.0
 This plugin just provides the Geb dependencies and a `create-functional-test` command for generating Geb tests in a Grails 3.0 app. For further reference please see the [Geb documentation](http://www.gebish.org)
 
 Geb tests are used extensively in the [Grails 3.x functional test suite](https://github.com/grails/grails3-functional-tests) if you are looking for examples.

+Additional Drivers
+=======
+
+To setup additional drivers you need to add the driver to your `build.gradle` for example:
+
+    testRuntime 'com.github.detro:phantomjsdriver:1.2.0'
+
+Then you need to create a `GebConfig.groovy` file to your `src/test/resources/` directory. For example:
+
+	/*
+		This is the Geb configuration file.
+
+		See: http://www.gebish.org/manual/current/#configuration
+	*/
+	import org.openqa.selenium.chrome.ChromeDriver
+	import org.openqa.selenium.firefox.FirefoxDriver
+	import org.openqa.selenium.phantomjs.PhantomJSDriver
+
+	waiting {
+	timeout = 2
+	}
+	driver = { new PhantomJSDriver() }
