To report a bug, suggest improvements to, or if you're having trouble installing or using the CLI, please open a GitHub issue.

You can also visit our support chat. We're just getting started with this, so activity is quite low, but the more people chat there, the more people will hang out.

If you're having trouble writing the code for an exercise on, then your best bet might be StackOverflow. Remember to search first, before posting, and remember that you're asking about the programming language problem, not the exercism problem.

Another option is to submit the code even though it doesn't pass the tests yet, and then go to your submission page to explain where you're stuck.

We welcome questions, and will do our best to help you out!
