For example, an org user may

(add-to-list 'help-quick-sections
             '("Org"
	       (org-ctrl-c-star . "Compute table/change heading ")
	       (org-ctrl-c-ret . "Table hline/insert heading")))

so that from org-buffers, C-h C-q adds a new section:

Org                                  
C-c *   Compute table/change heading 
C-c RET Table hline/insert heading   

Most likely users willing to customize `help-quick-sections’ would remove existing sections with commands they know well.

Do you mean documentation for the `help-quick-sections' variable?  How about turning this into a defcustom?  This would allow more advanced users to fully customize what “quick help” they want.
