== Documentation ==

The documentation below relates to ''using'' GHC.  For documentation about GHC's internals and building GHC, head over to the [https://gitlab.haskell.org/ghc/ghc/wikis/index GHC Developer Wiki].

These documents relate to the ''latest released'' version of GHC.
For ''earlier released'' versions click the relevant version on the
[http://www.haskell.org/ghc/download downloads page].  
For release candidates, look at 
[http://downloads.haskell.org/~ghc/ the GHC download directory].

== Collaborative documentation ==

GHC is a big system.  We try to document the core functionality (above), but
you can help by writing documentation yourself.  This section collects
documentation written in a collaborative way, by users and developers together.
Please help by adding new sections, and by clarifying and improving existing ones.
