We welcome contributions large and small to the Runestone Components. We welcome contributions from newcomers as well as seasoned Runestone hackers. You don't need to be an expert to make a contribution here. When I started this project I had barely written a line of Javascript, Runestone is a project that is all about helping people learn, if you learn by helping us improve Runestone that is even better!
Your next moves should be to check out the documentation <runestoneserver.readthedocs.org>_ It will guide you though installation and give you an overview of how Runestone is put together. The documentation is a work in progress so don't be shy about letting us know whats missing.
