Edited web page does not update

[Rob Belics]

I tried to dabble with updating documentation--specifically the web
site--using this link: https://docs.freebsd.org/en/books/fdp-primer/ I put
everything together and get the site to come up locally using Hugo as
outlined. However, I do not understand how to edit the web pages. First, I
can't find the home page (index) at all. Second, I tried editing the About
page doc/website/content/en/about.adoc, and rebuilt the whole thing, but
nothing changed when I refreshed the page.
