Tutorial plugin like iFixit.com ?

I will get back to share with you if I could find any.

That is not functionality provided by a plugin but how the site was designed and content is displayed.

What you’re looking for is a plugin that relates to user onboarding. Try searching for plugins using the terms: ‘user onboarding’, ‘onboarding’, and ‘tooltips’. Hopefully one of those will cover what you’re looking for in terms of design, style, and functionality.

Hi, I have been searching the same and I discovered that it’s actually a paid feature from dozuki:
