The wiki page the guide links to caused some confusion for our group,
e.g. Ctrl + F5 on a chromebook takes a screenshot rather than hard
reloading

Cache and Hard Reload will also clear assets that are downloaded after
page load (e.g. lazy loaded scripts) while just a Hard Reload will
only re-download assets which are explicitly listed in the DOM
