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.

Development of GHC

See the GHC Developer Wiki. The latest snapshot of the documentation for the next version can be found here.
