First of all, remember that JupyterLab is not stable yet and internal API are still changing quite a bit. The biggest part of your frustration is trying to find information about a project that is changing every week (should stabilize early 2018 for reference).

This lead to minimal effort writing documentation and example for users, as anyway the documents will be wrong a week later. So your confusion and lack of activity is normal for now.
