This tutorial explains how to create a simple SMS translator using Azure Functions, Twilio, and the Fun Translations API. To start, users need to set up an Azure account, Twilio account, and SMS-enabled Twilio number. Then, they create an Azure Function app, add a custom function with C# code, and enable NuGet packages for dependencies. The code uses the Fun Translations API to translate incoming SMS messages into pirate speak. The tutorial also covers how to handle rate limits from the Fun Translations API and provides guidance on using Azure Functions for small sections of code that can be reused across projects.
