From the beginning, the students actually repeated my steps, and in this way we gradually edited the text and pictures for almost the entire first lesson. Occasionally there was a problem that something stopped working for the students, but it was never a problem that could not be solved. Since I was actually "hidden" behind the computer, I was almost not nervous at all.
