Great questions. If you see that a language track has a particular course available (e.g Docker on Rust track), it means it's good to go. There are no hurdles to going through the stages. When a track is marked as beta, it typically means that the solutions & explanations for some stages on that language are coming soon — or that it doesn't have all the 4 courses supported in that language yet. You might also enjoy checking out our OSS repo where any one can contribute language support. We prioritise supporting different languages based on user demand, but if you want to get your hands on a particular language right away, we accept PRs from the community. https://github.com/codecrafters-io/languages https://github.com/codecrafters-io/languages
