I think all the changes are pretty much cosmetic so look good to me. The only major concern is about the way we introduce the registry concept - see my comment in the ticket.

Nonetheless, I think we need to do the next iteration. Further simplify intro and put an image (WIP on my end). Introduce some section between intro and example that provides some high level abstract overview of the Git and DVC commands you would use to organize the registry, example turned out to be too complicated and specific (e.g. we focus on one specific data set that we don't even reuse and we don't mention that registry contains all the data for all example, tutorials).
