 Make sure you have your LambdaTest credentials with you to run test automation scripts on LambdaTest Selenium Grid. You can obtain these credentials from the [LambdaTest Automation Dashboard](https://automation.lambdatest.com/build) or through [LambdaTest Profile](https://accounts.lambdatest.com/login).
 
 **Step 3:** Set LambdaTest `Username` and `Access Key` in environment variables.
-  * For **Linux/macOS**:
-  ```bash
-  export LT_USERNAME="YOUR_USERNAME" export LT_ACCESS_KEY="YOUR ACCESS KEY"
-  ```
-  * For **Windows**:
-  ```bash
-  set LT_USERNAME="YOUR_USERNAME" set LT_ACCESS_KEY="YOUR ACCESS KEY"

 ### Sample Test with NightwatchJS
 Let’s check out a sample **Nightwatch** framework code running on LambdaTest Selenium Grid. This is a simple Nightwatch automation script that tests a sample to-do list app. The code marks two list items as done, adds a list item and then finally gives the total number of pending items as output.
-```js
-//googleTest.js
-
-var https = require("https");
-var lambdaRestClient = require("@lambdatest/node-rest-client");
-var lambdaCredentials = {
-  username: process.env.LT_USERNAME,
-  accessKey: process.env.LT_ACCESS_KEY
-};
-var lambdaAutomationClient = lambdaRestClient.AutomationClient(
-  lambdaCredentials
-);
-module.exports = {
-  "@tags": ["test"],
-  TodoTest: function(client) {    
-    client
-      .url("https://lambdatest.github.io/sample-todo-app/")
-      .waitForElementPresent("body", 1000)
-      .setValue("input[id=sampletodotext]", "Complete LambdaTest tutorial.")
-      .click("input[id=addbutton]")
-      .pause(1000)
-      .end();  
-
-  },
-  after: function(browser) {
-    console.log("Closing down...");
-  },
-  afterEach: function(client, done) {
-    if (
-      process.env.LT_USERNAME &&
-      process.env.LT_ACCESS_KEY &&
-      client.capabilities &&
-      client.capabilities["webdriver.remote.sessionid"]
-    ) {

-      lambdaAutomationClient.updateSessionById(
-        client.capabilities["webdriver.remote.sessionid"],
-        { status_ind: client.currentTest.results.failed ? "failed" : "passed" },

-          if (!error) {
-            client.pause(1000)
-            done();
-          }
-        }
-      );
-    } else {
-      console.log("Test Run Successfully!");
-      client.pause(1000)
-      done();
-    }
-  }
-};

 ```
 ### Configuration of Your Test Capabilities
 **Step 4:** Below is the `nightwatch.conf.js` file where we will be declaring the desired capabilities. Since we are using remote webdriver, we have to define which browser environment we want to run the test. We do that by passing browser environment details to LambdaTest Selenium Grid via desired capabilities class.
 
-```js
-//nightwatch.conf.js
-
-module.exports = (function(settings) {
-  console.log(settings["test_settings"]["default"]["username"])
-  if (process.env.LT_USERNAME) {
-    settings["test_settings"]["default"]["username"] = process.env.LT_USERNAME;
-  }
-  if (process.env.LT_ACCESS_KEY) {
-    settings["test_settings"]["default"]["access_key"] = process.env.LT_ACCESS_KEY;
-  }
-  if (process.env.SELENIUM_HOST) {
-    settings.selenium.host = process.env.SELENIUM_HOST;
-  }
-  if (process.env.SELENIUM_PORT) {
-    settings.selenium.host = process.env.SELENIUM_PORT;
-  }
-  return settings;
-})(require('./nightwatch.json'));
