You must judge the length of your tutorial, because you are the one that knows the time required for each step. we put no length limits!
Just so you know, the regular length of our video tutorials is from 2 to 30 minutes, and you can always split the video in two parts. But we also make longer tutorials which we call “courses” that might last 1:30 and are divided by lessons.
For written tutorials the average is around 20 steps , but as we said before, there are no limits.
