This of course needs SSH access to the flamenco.io website.
Run `hugo --serve` from the `web/flamenco-io-site` directory to simply
run an in-memory copy of the site, and browse it locally at
http://localhost:1313/
Building this site requires Hugo (not yet included in the README or in the
installation of dependencies in the Makefile). Still very much work in
progress, this is basically the [Geekdocks theme][1] + one page.
