Let's say my mobile app has a 3 intro screens Screen1, Screen2, Screen3 that are shown at the 1st launch. When Screen1 and Screen2 screens are swiped right the next screen is shown. Also there is a "skip" button on them that redirects to the Main Screen. On Screen3 screen there is a "start" button which also redirects to the Main screen. Screen2 and Screen3 can be swiped left to see the previous screen.
I need to draw a flowchart of it. Which way us more canonical? Certainly the 2nd way is more compact but do you consider it ok?
