Yes but this would make much more sense if used as help topics, i.e.
"confused about how to upload your portfolio? click here for an interactive demo"
"confused about how to upload your portfolio? click here for an interactive demo"
There are free solutions too (e.g. http://bootstraptour.com/ )
(But, I would prefer text-based documentation. You can still have videos or animations too if wanted, though.)
I guess a video would do the trick though
