With continued growth of the RMG development team and user-base, good software development practices have become increasingly important. In recent years, additional emphasis has been placed on implementing best-practices for open-source software development. All RMG source code is publicly available on GitHub. Code review and continuous integration testing are emphasized as part of the development workflow, which has been formalized via official contributor guidelines. Elements of git-flow and semantic versioning have also been implemented into the development workflow to improve version release planning.
