Contributing to the Glasgow Haskell Compiler
So you've decided to hack on GHC, congratulations! We hope you have a rewarding experience. This file will point you in the direction of information to help you get started right away.
The GHC Developer's Wiki
The home for GHC hackers is our GitLab instance, located here:
https://gitlab.haskell.org/ghc/ghc
From here, you can file bugs (or look them up), use the wiki, view the
git history, among other things. Of particular note is the building
page, which has the high level overview of the build process and how
to get the source:
