I just wanted to mention that I am in the middle of a big documentation push. Additions to the User Guide and much expanded API reference pages are some of what I have just deployed. I will be adding more leading up to a tutorial that I am giving at PyData London later this month (and I will also post a link to the full tutorial talk here once they are uploaded to Vimeo). Please check out the full Bokeh docs at
Please let me know here or in a GH issue, if there are particular areas that you think need special improvement are addition. As always we would love to have more contributors, so if you are looking for an open-source project to get involved in, whether you hare submitted 100 PR's or none yet, please consider pitching in to Bokeh!
