Rojo is a fairly complex tool to adopt, but there's a community willing to help!
The Roblox Open Source Community Discord currently hosts a Rojo support channel, #rojo, that is a great place to get help as problems come up.
If you find anything that looks like a bug or have ideas for how to improve Rojo, feel free to file an issue on Rojo's GitHub issue tracker.
Rojo's primary maintainer is also available on Twitter, @LPGhatguy.
