The documentation for command-line flags uses “foo” and “bar” as placeholders without clarifying that they are generic examples of a key and a value.
New readers unfamiliar with this convention may interpret them as literal parameters. Suggest adding a short note as given explaining that “foo/bar” are placeholders for any config key/value.
Update:
This branch includes both a minor clarification and a full rewrite. I’m happy to separate them into two PRs if preferred.
