You first installed the Amplify Command Line Interface and configured your profile right at the console.
You then initialized a new Amplify backend project on the command line which creates packages and dependencies right at the root of the TravelBuddy project.
You then configured Amplify on the client with a few import statements to our src/App.js file.
You then added User Authentication with Amazon Cognito with the help of the AWS Amplify CLI with withAuthenticator.
On the challenge exercise, you incorporated a custom Sign In / Sign Up form by directly calling the Auth Class methods.
