Riel is a version control system focused on fast, easy, smart merges. Developer's time belongs to their code, not our merges.
You just need to contribute. Fork a repository (preferably Riel), commit, and open a PR, commenting that you want access to the foundation.
Simply open a pull request, any contributions are welcome
