what does adorn mean in this context? GDP

[Jay Hamilton]

I'm working on the balloon section of Editorial and in that section is this 
statement

There are two music functions, balloonGrobText and balloonText; the former 
takes the name of the grob to adorn, while the latter may be used as an 
articulation on a note. The other arguments are the offset and the text of the 
label.

the words after the semicolon (;) look like they make sense but adorn and 
articulation don't really make sense to a common English reader (me) can 
someone explain what is meant here so I can translate it into something I might 
understand?

Thanks


Yours-
Jay
