This tutorial covers how to build a straightforward Django project with SMS capability that transmits messages to multiple recipients using the Twilio SMS API. The application uses the Twilio helper library to make it easier to send text messages from Python, and requires a free Twilio account to authenticate and receive credentials. The code includes setting up a virtual environment, installing dependencies, creating a Django project, defining URLs for sending SMS, coding the broadcast app, accessing the Twilio SMS API, testing an SMS broadcast, and wrapping up the application.
