The tutorial guides the reader in creating an automated SMS notification system using AWS Lambda, JavaScript, and Twilio's SMS API. The goal is to receive the latest currency exchange rate from GBP to EUR on a mobile phone through SMS. The project involves setting up an AWS account with sufficient permissions, installing Node.js and required dependencies, and configuring the serverless Lambda function in index.js. The code uses request-promise-native for HTTP requests to the Fixer.io API and Twilio's SMS API to send notifications. The tutorial also covers local testing using lambda-local, deployment on the AWS web console, remote testing, reading logs, and provides a recap of the project and ideas for future experiments.
