The C3 language is still in its design phase, which means functionality and specification are subject to change. That also means that any contribution right now will have a big impact on the language. So if you find the project interesting, here's what you can do to help:

• Discuss the language on the C3 Discord https://discord.gg/qN76R87
• Suggest improvements by filing an issue: https://github.com/c3lang/c3docs/issues/new
• Offer to work on the compiler being written here: https://github.com/c3lang/c3c
