Contributing to Open Source Clojure Projects

One of the fastest ways to get better at Clojure is to read real code and participate in the community. This chapter helps you navigate Clojure repositories, understand common conventions, and contribute in ways that maintainers appreciate.

If you have contributed to Java projects before, the social side will feel familiar: good issues, small PRs, reproducible bug reports, and respectful communication. The differences are mostly in tooling and idioms—namespace organization, REPL workflows, and the shape of tests.

The goal is to make open source feel approachable, so you can learn from real-world codebases and build credibility in the ecosystem.
