where is the help of captivate 9?

Dear sirs,  I can't find where is the help document of captivate9, please help me, thanks.

I am using captivate9 to publish a project as html5 files, I don't understand some options on the publish screen, so I press F1 to acquire help and I successfully find the help page:Publish projects as HTML5 files with Adobe Captivate‌ . But the help is not enough, there is not explain for each options. I need detail help where I can find the function explain for each options on the operate screen.

Thanks a lot.
