Welcome to the GHC Developer Wiki

This is the home for GHC developers, one place for all the resources related to developing GHC. If you're only interested in using GHC, then you probably want  The GHC home page instead.

If you are a new GHC developer, and just want to get started, then don't read any more of this page; instead look at Getting Started (which is always in the sidebar under "Joining in").

If you are a regular GHC developer, then the rest of this page, and the sidebar, are for you.

Please help improve the GHC developer's wiki

Please help us improve the information on the GHC developer's wiki. You can easily do this by editing the wiki directly. Just register an account, and then edit away. Alternatively, log in as user guest with password guest (but we'd prefer you to create an account, because it enables us to contact you if necessary). The "Help/Guide" link at the top of every page gives a good description of the markup language etc.
