Scala is a community-based language. A few people at Lightbend and the Scala Center are paid to facilitate, but ultimately Scala succeeds or doesn't because of you. This talk is about how to participate effectively in open-source work happening in the scala/* repositories on GitHub. You'll learn the overall lay of the land as well as advice on contributing in specific areas such as websites and documentation, issue reporting, Scala modules, the Scala standard library, and even the Scala compiler.
