Making confusing Docs Easy to understand, Website Idea

Hello Indie Hackers,

I hope you are all having a great time building the next great big thing!

Yesterday I had an idea for an Education Website that has easy to follow video tutorials and articals for understanding how to build on the Biggest APIs, SDKs and anything else that has confusing, hard to understand documentation.

The problem this service would solve is the ability to learn how to create things without having to read confusing and hard to follow documentation!

I have a few questions I would like to ask to help validate the idea:

1. Is there a need for Easy to follow documentation on the biggest APIs, SDKs etc…
2. What price would you pay, is it a one time fee, monthly or yearly?
3. What features would you like to see in a product like this?
4. Do many Developers have the problem of not understanding Dev Documentation or is it just me?

I thank you so much for reading this & I hope to hear from you!
