Before contributing to the compiler implementation please read our style guide first. Pretty much anything can be a contribution, from a tiny typo fix, to an entire feature implementation - anything is possible. Another way of contributing to the compiler implementation is editing and giving suggestions related to the compiler design writeup.
Before contributing to the language design implementation please read our language design writeup.
