Kotlin is an Apache 2 OSS Project. The source code, tooling, documentation and even this web is maintained on GitHub. While the majority of the team works at JetBrains, there have been nearly a hundred external contributors to the Kotlin Project and we are always looking for more people.
If you want to contribute to the code, go to GitHub and check out the latest version and follow the instructions on how to build Kotlin from source. After that, you can start picking some pending tasks on the issue tracker. Make sure you look for issues tags with Up For Grabs as these are some of the easier ones to get started with.
We need a lot more documentation. If you’re interested in collaborating, please feel free to check out the source code to this site on GitHub and send a Pull Request. The site is built using Markdown and Jekyll.
Have you created a tutorial or video on Kotlin? Please let us know. We’d be more than happy to have it featured under Community Content.
If you’ve given or are giving presentations on Kotlin, let us know. We’ll feature it on the list
Kotlin ships with a very small runtime and it’s the aim to keep it that way. We believe other functionality that is missing from the standard runtime library can be developed as Kotlin Contributions under the Kotlin-X umbrella or as individual projects by community members. If you have a library that think others might find useful, let us know. If you want to contribute to any of the existing ones, check them out.
Kotlin is a new language but we have high hopes for it and we need people that believe in it to spread the word!
