 Getting started
 ===============
 
-A good starting point is to work on the `open issues on GitHub <https://github.com/emscripten-core/emscripten/issues?state=open>`_. Many issues can be resolved without an in-depth knowledge of compiler internals, and this is a great way to learn more about the project.
