monitoring-stats.html is too impenetrable

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/9.6/monitoring-stats.html
Description:

There needs to be a tutorial page explaining how to use pg_stat_all_tables
to find missing indexes, or maybe just an example on monitoring-stats.html
which is hopelessly inaccessible to a non-expert. I would have never been
able to figure out anything close to the solution at
https://www.reddit.com/r/PostgreSQL/comments/e0rx8l/i_was_missing_a_single_index_and_omgf_everything/
from the existing docs. Thank you for your kind consideration of this
request; please do not hesitate to send instructions for how to submit a
pull request for this, as I would gladly do so. Best regards, -Jim
