Well, I think "official documentation" isn't the right word, because 
Ruby is an ever-changing community project and there are many different 
implementations (CRuby, JRuby, Rubinius etc.).

Personally, I think the Ruby book by Matz and Flanagan is a pretty good 
and complete reference.

There are also some formal specifications like for example this one: 
http://www.ipa.go.jp/osc/english/ruby/Ruby_final_draft_enu_20100825.pdf

But of course they can never cover each and every aspect and be 
absolutely up to date.
