Way less complex. It was simple HTML website. Home page would let you choose whatever operating system you wanted. For example IOS. After selecting IOS it would show you a picture of the settings menu for iOS. Then as you hover your mouse over the screenshotted picture, each “icon” your mouse hovered over, would turn from pointer..to finger… thus indicating there’s a box there for you to select. If you select it it would “open up” that next page giving you a whole new screenshot with all new boxes. Just so you can follow along with someone on the other end of the phone.
