-## Notes
-* You can view your test results on the [BrowserStack Automate dashboard](https://www.browserstack.com/automate)
-* To test on a different set of browsers, check out our [platform configurator](https://www.browserstack.com/automate/java#setting-os-and-browser)
-* You can export the environment variables for the Username and Access Key of your BrowserStack account. 
+### Migrate from Vanilla Cucumber to use Testng Runner 
+* If you are using Vanilla Cucumber CLI, you can migrate to use TestNG Runner with BrowserStack using the below command :
+```
+mvn archetype:generate -DarchetypeGroupId=com.browserstack -DarchetypeArtifactId=cucumber-testng-archetype -DarchetypeVersion=1.0 -DgroupId=com.browserstack -DartifactId=cucumber-testng-archetype -Dversion=1.0 -DinteractiveMode=false
+```
+* Run your tests using `mvn test`
+* To use specific `@CucumberOptions` in generated class `BrowserStackCucumberTestNgRunner`, refer - https://javadoc.io/static/io.cucumber/cucumber-testng/5.0.0-RC2/io/cucumber/testng/CucumberOptions.html
 
+## Using Gradle
+
+### Run sample build
+
+- Clone the repository
+- Install dependencies `gradle build`
+- To run the test suite having cross-platform with parallelization, run `gradle sampleTest`
+- To run local tests, run `gradle sampleLocalTest`
+
+Understand how many parallel sessions you need by using our [Parallel Test Calculator](https://www.browserstack.com/automate/parallel-calculator?ref=github)
+
+### Integrate your test suite
+
+* Install dependencies `gradle build`
+* Following are the changes required in `gradle.build` -
+    * Add `compileOnly 'com.browserstack:browserstack-java-sdk:latest.release'` in dependencies
+    * Fetch Artifact Information and add `jvmArgs` property in tasks *SampleTest* and *SampleLocalTest* :
   ```
-  export BROWSERSTACK_USERNAME=<browserstack-username> &&
-  export BROWSERSTACK_ACCESS_KEY=<browserstack-access-key>
+  def browserstackSDKArtifact = configurations.compileClasspath.resolvedConfiguration.resolvedArtifacts.find { it.name == 'browserstack-java-sdk' }
+  
+  task sampleTest(type: Test) {
+    useTestNG() {
+      dependsOn cleanTest
+      useDefaultListeners = true
+      suites "config/sample-test.testng.xml"
+      jvmArgs "-javaagent:${browserstackSDKArtifact.file}"
+    }
+  }
