Create staff for Congas

[George]

I'd like to notate a congas part in one of my lilypond scores,
and I found the official lilypond documentation for doing so:

http://www.lilypond.org/doc/v2.16/Documentation/notation/common-notation-for-
percussion#percussion-staves

However, even with the aid of the docs, I don't know how to create a conga 
staff.

I'm struggling to understand:
"set the property drumStyleTable in context DrumVoice"

Please, can someone post an example conga part they created?

Any help will be much appreciated!

Thank you all,
George
