Read this wiki for Perl 6 information that’s new or at least recently curated. (The cabal set this up as a new Perl 6 wiki in 2012. It is being maintained as of 2013.)
(As a complement/alternative, use the google custom search engine 6now to search selected known new and/or known worthy resources including some of those linked from these wiki pages.)
Some information will be about Perl 6 in general, such as the Official Perl 6 Documentation (the most formal and canonical of all Perl 6 doc). Some will be specific to particular pieces, eg the Rakudo, Niecza, Perlito, and Pugs compilers. For more about the various Perl 6 implementations, see the Implementations Faq.
Here is an overview of Some Major Parts of Perl 6.
To get started with Perl 6, here’s a list of Various Tutorials.
Expect links to existing high quality content, such as doc.perl6.org, or the curated Categorized External Articles and Categorized External Videos, plus pages freshly written in this wiki if existing docs are found wanting and someone has had tuits, such as the introductory Mostly Harmless Docs/Main.
