In Safari, the favicon preload is an error (<link rel=preload> cannot have the empty string as 'as' value). In Firefox, that is classified as a warning.

message? It's misleading... Also, and this is a platform-specific issue, using Safari, if you click on that link it shows you a blank page (about:blank)
or maybe add in the docs something to that effect everywhere (less efficient)
I see in Install Plone with Buildout — Plone Documentation v6 there is " Now you can visit http://localhost:8080 in your browser." but it isn't obvious that this is an important difference in the URL nor what happens if you don't.
Pull requests welcome to improve docs. Be careful that your language stays in the context of a how to guide and doesn't stray into a conceptual guide, according to Diátaxis.
