You are welcome to contribute code. Unless your contribution is really trivial you should get in touch with me first — this can prevent wasted effort on both sides. You can send code both as a patch or a GitHub pull request.
Note that PEG.js is still very much work in progress. There are no compatibility guarantees until version 1.0.
