Hey Bobi,
Probably you are getting confused because you are looking at the instructions for ScrollReveal 3.x while our templates use ScrollReveal.js 2.x
These two versions are very different. They work in a completely different way.
I do not have any plans for updating to v3.x because it really does not fit our case as good as v2.x. I also opened an issue about that and discussed all this in details with the ScrollReveal.js developer. You can read everything in
this discussion on Github.
Julian (the developer of ScrollReveal.js) promised that he will continue to maintain v2.x as well. So there's nothing we should worry about
And regarding the v2.x instructions and keywords - you can find everything
here and
