== Background
We have added the items required in the ToC instrumentation specification (https://docs.google.com/spreadsheets/d/1CAXGqV2JR_bE0ulo9EU3I74Jm0Ln9z1u2CjC6zvra7I/edit#gid=0) which will allow us to perform an A/B test on the new Table of Contents focused on answering the following questions:
# Is the new table of contents is used more frequently than the previous table of contents
# Does the new table of contents reduce the need to scroll back to the top of the page
# Does the new table of contents decrease the time people spend scrolling/scrolling quickly (if possible)
# How does the new table of contents affect the time spent on a page
