Welcome! I'm going to show you how to install Qt Creator, the program used to write code in CS106B/X/L. You'll have to download over 2 Gb of files, so this process may take some time to finish.
In order to make the installation process a little bit easier, each step includes an animation showing what to click on. Don't worry if the animation goes by too fast - it will repeat after a short period of time.
Open up Safari and proceed to the next step to get started!
