LGTM, though I have a lot of edit suggestions.

Ordered list enumeration (1. repeated) is only available when writing a Hugo page.

It's very basic, but since explicit instructions are given for everything else, the example could also give the command to view the logs.

I may convert this to a proper documentation page at a later point: see #6572 for an example.
