Software handbook / tutorial as pillar content?

Hello,

I'm wondering whether that would work:
A software handbook / tutorial nicely formatted as a super long pillar content.
With

• screenshots
• error messages
• internal links to video tutorials on how to use the software
• internal links to further info on sub-sections on the software

And the keyword sth like: how does [software] work or similar.
Did anybody try this? Is it worth the time investment? How to get such a best in class content afterwards on top of Google...
