How to post a HOW TO VIDEO and where?

I have created a short how to build your profile page video that I have uploaded to Youtube.

I realize that in talking with some new users, they required me to walk them through on how to create their profile page. So I had this idea of creating a video showing them how to do it.

So my question is, when someone registers a new account and then they go to their email to confirm it, what would be the best way to make sure they see this "How to video?". Should I make a link of some sort back to Youtube or create some sort of a page and have that video embedded into it?

Thanks!
