 Start from [this tutorial](https://docs.aws.amazon.com/lambda/latest/dg/services-apigateway-tutorial.html#services-apigateway-tutorial-api) or the AWS docs above to create a REST API that exposes `calculate`.
+
+After setting up API Gateway, locate the API call logic in your frontend code (where it currently calls localhost). Replace the localhost URL with the API Gateway endpoint URL.
+
 Then, coordinate with your team to make sure that invocations of `calculate` call the calculator's backend lambda code.

 Amplify integrates with [Amazon S3](https://docs.aws.amazon.com/amplify/latest/userguide/hosting.html) to store and serve static assets like HTML, CSS, and JavaScript files. It provides an automated deployment pipeline that syncs with your GitHub repository and updates the frontend whenever changes are pushed to the main branch.

 ### 4. Use Github actions to automatically deploy on each push to main
 
-Finally, you will use a Github action to automatically:
-1. Deploy your packaged backend lambda code.
-2. Deploy your frontend code to S3.
-3. Deploy the updates made on S3 to Amplify endpoint.
+After getting hands on experience with each service , you will use a Github action to ensure that updates are deployed automatically on each commit to the main branch
+
+The CD pipeline will perform the following tasks:
+1. Deploy the packaged backend Lambda code.
+2. Deploy the frontend code with the updated API endpoints to S3.
+3. Trigger AWS Amplify to redeploy the frontend from S3.
 
 In order to do this, you will need to allow Github to authenticate to AWS.
 Follow the [Github documentation](https://docs.github.com/en/actions/security-for-github-actions/security-guides/using-secrets-in-github-actions) to safely use your AWS secrets in CD. [This AWS blog post](https://aws.amazon.com/blogs/compute/using-github-actions-to-deploy-serverless-applications/) describes some (basic) best practices for generating and handling AWS authentication secrets in CI; navigate to the "Configuring AWS credentials in GitHub" section of the tutorial.
 
+Next, you will create one or more .yml files under the .github/workflows/ directory in your repository.
+For example:
+.github/workflows/deploy-aws-s3.yml (for AWS S3 deployment)
+.github/workflows/deploy-aws-lambda.yml (for AWS lambda deployment)
