Please read our public guidelines for contributing.
The first thing you’ll need to start contributing is a source checkout of the Git repository. The Open Dylan sources are hosted on GitHub, along with sources for the opendylan.org web site and various other repositories. If you don’t yet have a GitHub account and ssh keys, now is a good time to get them.
To checkout the main “opendylan” repository:
git clone --recursive firstname.lastname@example.org:dylan-lang/opendylan.git
You will want to fork this repository so you can push changes to your fork and then submit pull requests.
