What it should look like:

Have a bunch of checkboxes at the top, one for each buzzword, each technology and all other things a 12 year old wouldn't be familiar with.

You check which you think to be familiar with and all other things unfold a short description with links to similar interactive documents.

Each section comes with 1-5 star rating for how well the reader understood your explanation.

Then you gather the data as the subjects suffer though the tutorial.

If people come from specific backgrounds further tailor the explanation for them.(Like babazoofoo for C++ developers.)

Let there be a browser extension or an API that checks (and hides) the familiar boxes for you.

I didn't say it was possible to make. It would be glorious to have. If you know all the tech involved the whole thing implodes into a one line code example.
