The Crystal official code repository is on GitHub, so any bugs you find in either the language, compiler or standard library should be reported here - and pull requests are always welcome.
The Crystal Forum is the first to-go place for any general discussion. Feel free to ask a question, share your project with others, ask for guidance and best practices, offer your help contributing to a project, or anything else Crystal-related.
New Releases, Use Cases and more
In the official Crystal blog you can find the detailed announcements for new releases, some interesting use cases, the rationale behind some of the language's design decisions and things the team write around the code they usually write.
We also accept posts from guest writers, so if you have something awesome you have built with Crystal, contact us and we'll be happy to have you featured on the blog.
