Functionality is not clear enough for non-Drupal users

Problem:
I told some guys "Your project should have a test/demo facility like Drupal has with Simplytest.me"...
They came back asking so, there's a search field, what do i do there?
I went over to the site and thought
"Right, what a 'Project' is, and that DRUPAL is a project, is already quite insider knowledge... this is really bad", i thought.
This might need a link to "modules", "themes" and "distributions"...

Only on 2nd look i saw the "What is this?" Badge... I think it's maybe a bit too stylish, not resembling a classic "help" link, and, at least on big screens, too far away from focus.

Ideas:

1.
Change
"Start typing the name of a module, theme or distribution..."
to
Start typing a module-, theme- or distribution- name or 'drupal' for drupal core..."

2.
Add links to modules, themes, distros just below the input field

3.
Move / restyle the Help-link to be more close to the search-field

4.
Add an animated gif below the input field, to explain...

5.
Simply put the content of the "What is this" Page on the frontpage directly... It's minimalistic enough...

6.
Explain that Drupal is a valid Project-name, that's currently only communicated by the Screenshot image on the "What is this" page
