Hypothesis is a centralized web service that allows you to comment and annotate arbitrary web pages across the web. It allows your readers to log in and comment on your book.


Hypothesis is activated on this page. You can see the web overlay by clicking on the < button in the upper-right corner of this page.

Activate Hypothesis

You can activate Hypothesis by adding the following to your _conf.yml file:

    hypothesis: true

This will add a Hypothesis overlay to your documentation. This extension simply activates the Hypothesis JavaScript bundle on your Sphinx site.

When you build your documentation, you will see the Hypothesis overlay to the right of your screen.
