## AI overview

This tutorial introduces essential Kotlin coroutine concepts for performing multiple tasks concurrently, such as making network calls while updating a screen. It aims to provide a foundation for day-to-day coding and more advanced coroutine concepts.

## Source excerpt

When you're on hold during a phone call, you might also check your email. While brewing coffee, you might also cook breakfast. And while driving a car, you might listen to a podcast. In the same way, sometimes it's helpful for the software that we write to do more than one thing at a time. For example, it could make two or three network calls at one time--all while updating the screen to show the progress of each call.
